A foundational aspect of Materials Science is to understand, characterize, and
predict the underlying mechanisms and behaviors of materials. Computational
modeling and simulation provide many critical insights in these efforts, but
also require constant development, validation, and application of numerical
techniques.
This symposium invites abstracts on the development and application of novel
algorithms for materials science and engineering. This year’s symposium will
especially focus on (but is not limited to) the following topical areas:
Novel methodologies for data mining, machine learning, image processing,
microstructure generation, high-throughput databases and experiments.
Surrogate and reduced-order modeling, and extracting useful insights from large
data sets of numerical and experimental results.
Algorithm development to enhance or accelerate classical computational
materials science tools including density functional theory, molecular
dynamics, Monte Carlo simulation, dislocation dynamics, phase-field modeling,
CALPHAD, crystal plasticity, and finite element analysis.
Development of novel physics-based, multiscale, multi-physics materials
modeling.
Algorithm development for fusing and evaluating the quality of multimodal data
and their incorporation into computational materials workflows.
Uncertainty quantification, statistical metrics from image-based synthetic
microstructure generation, model comparisons, and validation studies related to
novel algorithms and/or methods in computational material science.
Development of novel methodologies for the analysis and management of data,
including best practices for `FAIRization’ of data (FAIR: Findable, Accessible,
Interpretable, Reproducible), as well as best practices for research software
development and dissemination.
Selected presentations will be invited to submit full papers for a IMMI issue
(5-10 papers).
Materials processing involves inherently interlinked and complex chemical,
thermal, mechanical, and physical operations, spanning from the extraction of
raw materials to the shaping and heat treatment of final products. This
symposium is dedicated to improving the understanding of materials production
and process technology through multiple experimental and modeling techniques.
At TMS2025, this symposium will focus on first principle and applied studies of
thermodynamics and rate-governed phenomena, including reaction kinetics and
meso-, macro-scale transport of mass, momentum, and energy throughout the
sequence of processing operations. Studies that provide the necessary
framework for improved understanding of materials manufacturing unit operations
leading to optimized process designs and control are especially encouraged.
This symposium is cross-functional in nature and is open to all materials, such
as ferrous and nonferrous metals, composites and ceramics, and their relevant
synthesis and manufacturing techniques. Examples of subjects include, but are
not limited to:
• Thermodynamic modeling (i.e., CALPHAD-based methods) for the optimization of
alloy solutions, slag compositions, and other types of materials.
• Mass and energy balance simulations of material processing systems using of
software such as FactSage, MPE, HSC-SIM and METSIM.
• Both experimental and numerical studies on kinetic rate theories pertaining
to crucial material processes such as chemical reactions, diffusion, nucleation
and phase transformations, and solidification.
• Numerical modeling and simulation, such as computational fluid dynamics
(CFD), of multi-scale transport phenomena in unit operations.
• Development and application of process simulations that utilize a combination
of thermodynamic, kinetic and transport equations to simulate and/or control
individual unit operations and/or plants.
Materials processing abstracts on topics other than thermodynamics and rate
phenomena will also be considered for presentation.
Digitalization and automation are constantly changing the scene of material
processing. In this symposium, particular emphasis is given to the role of
modeling approaches in improving the recycling processes. Digital approaches
can enhance process control, evaluate processing parameters and the quality of
final products. More specifically, the role of process models and simulation
tools for the optimization and development of metallurgical processing will be
explored. Particular focus will be given to monitoring minor elements. Further,
modeling approaches, such as machine learning algorithms, and thermodynamic,
kinetic, and multiphase modeling tools for integrating secondary sources into
the production lines, will be highlighted.
The purpose of the furnace containment system is to hold both process materials
and energy associated with pyrometallurgical processes. The methods in which
the challenges of containing corrosive and abrasive materials at extreme
temperatures will be addressed, whether they are used across commodities or
technology specific. There is much to be learned from cross-commodity and
cross-technology perspectives. The intention of this symposium is to create a
platform for the exchange of ideas on the challenges, solutions, failures, and
successes in furnace containment designs and applications. Bringing together
perspectives from industry, design houses, and research institutions will be
ideal. For the symposium, the furnaces associated with solid-state processes
are included although the focus will be smelters.

1. Advances in furnace lining design philosophies
2. Advances in furnace design configurations and other design considerations
3. Problems experienced and their solutions implemented during construction
and commissioning
4. Integration of new concepts into old smelters
5. Back to basics: refractory materials, shells, and cooling systems
6. Maintaining and monitoring
7. Process control and slag design

This symposium is dedicated to materials processing including: synthesis,
analysis, design, monitoring, and control of metals, materials, and
metallurgical processes and phenomena. This symposium is cross-functional in
nature and is open to all materials and their relevant synthesis and production
processes. At TMS 2024 a particular focus will be placed on the fundamentals of
iron and steel production including ladle processing, casting, rolling,
forging, and subsequent surface treatments. Typically dedicated to the
fundamental understanding of materials manufacturing processes, this symposium
is also dedicated to advances which increase efficiency, yield, or
environmental friendliness of said processes. As non-limiting examples subjects
might include:
* Use of Artificial Intelligence or Big Data in the control or optimization of
industrial processes.
* Modelling or optimization of recycle streams and scrap loops.
* Measurement and control of process parameters
* Modeling transport phenomena in materials processing and metallurgical
processes involving iron, steel, nonferrous metals, and composites.
* Thermodynamics, kinetics, and physical chemistry of materials processes and
modelling thereof.
Materials processing abstracts on topics other than iron and steel may be
considered for presentation.
Accurate and reliable measurements are the foundation of well-controlled
processes. The high-temperature environments inherent in many industrial
operations, including metal smelting and casting, heat treating, and nuclear
power generation make measurements challenging due to the instability of
electronics at elevated temperatures, increased rates of corrosion and
mechanical degradation of instrument materials, and dust formation and
infiltration. In order to effectively measure the conditions in these
processes, the instruments and equipment used in these applications must have
excellent chemical stability, resistance to thermal shock, and mechanical
integrity over a wide range of temperatures. Accurate measurement is necessary
but not sufficient for successful high-temperature processes; informed use of
these measurements by means of integrated control mechanisms is also critical
for maintaining stable and productive operations.
This symposium will focus on exploring (1) proven and/or novel measurement
techniques for use in high-temperature environments (including measurement of
temperature, velocity, pressure, chemical composition, or other parameters) and
(2) process control schemes employed in these environments, with preference
given to those implemented in industrial operations.
The industrial processes of interest include, but are not limited to:
- Metallurgical production furnaces
- Heat treating furnaces
- Casting line operations
- Molten salt electrolysis cells, including Hall-Heroult cells
- Nuclear reactors
- Gas turbines
The ninth edition of the "Frontiers in Solidification" symposium series is
dedicated to Jonathan A. Dantzig, a recognized world leader in the field of
solidification, casting, and computational modelling of materials processing
and microstructure development. Starting his career in process modelling, Jon
later tackled more fundamental aspects of solidification modeling at the
microstructure level. Therefore, this edition is particularly focused on
process and microstructure modeling, even though contributions across the
entire field of solidification are welcome.
These include:
- Fundamental aspects of solidification which advance our understanding of how
microstructures develop and evolve during solidification experiments or
processes;
- Contributions which put forward original interpretations, observations of
novel phenomena, and outstanding challenges from both fundamental and applied
perspectives, as well as transfer of fundamental knowledge to practical
applications;
- Investigation methods including theory, experiments, characterization,
modeling across all relevant length and time scales, as well as data-driven
approaches;
- Contributions that combine novel characterization techniques, challenging
property measurements, and computational simulations across scales are
especially encouraged.
This symposium is dedicated to materials processing including: synthesis,

The absence of gravitational effects such as thermal and solutal buoyancy
enables investigation of a large range of different phenomena in materials
science. These reduced-gravity experiments can isolate phenomena otherwise
obscured in ground-based experiments, leading to new discoveries that can
improve materials and processes here on Earth. Long-term experiments in
microgravity have a long history – from the early days of spaceflight to
current experiments onboard the International Space Station. Other platforms
for reduced gravity experiments include drop tubes and towers that provide
seconds of reduced gravity, aircraft (parabolic flights) that provide tens of
seconds, and sounding rockets that provide hundreds of seconds. Abstracts are
solicited in all areas of materials research employing reduced gravity,
including crystal growth, containerless processing, materials processing and
properties, and experimental facilities for materials research. This symposium
continues the series "Experimental Methods in Microgravity Materials Research"
and "Materials Research in Reduced Gravity", which have been recurrently held
at the TMS Annual Meeting since the 1980s.
Many a metallurgist fell in love with pyrometallurgy after witnessing a smelter
being tapped. There is something magical in the combination of light, energy
and danger that simultaneously stirs the primal instincts to ‘run for your
life’ and ‘go closer and have a look’.
But tapping a smelter is not an easy task.
Much engineering go into the design of the tap-hole. Due to the aggressive
nature of the process, material selection is as important as layout. The design
process kicks off with a set of design criteria, which needs to be revised as
the results of laboratory, compational fluid dynamics (CFD) and time-and-motion
studies become available. The tap-hole life-cyle is taken into account with
designers addressing the requirements for installation and operability as well
as for maintenance. Matters such as online monitoring of the taphole wear,
handling of liquid products, and extraction of fumes are all taken into
account.
Though tap-hole life can be improved with proper design, a good design can be
destroyed with incorrect tapping practices and equipment. Despite the harshness
of the tapfloor environment, it requires precision equipment and operating
practices. The design and maintenance of the drilling, tapping and plugging
equipment and materials plays an equally important role in tap-hole life and
tapfloor safety. As does protective equipment. Operators want the tap-hole life
to be as long as possible since tap-hole failures is often the cause for a
reline—a very expensive exercise in an upcycle when the cost of a new lining is
small compared to the loss in production. Managing the maintenance and reline
schedule is a challenge with lessons often learned the hard way.
The first thing students are taught in pyrometallurgy courses is how to compile
a mass and energy balance for a smelter. An accounting mass and energy balance
is used not only to schedule furnace taps but also to make process decisions.
Process variables measured during or after tapping are important inputs to a
workable mass and energy balance.
Even though much has been done to make the tapping process as automatic as
possible, tapping of smelters cannot be done without labour. Tap floor
operators work in harsh environments where safety is of utmost importance.
Selection of suitable personnel and intensive training is required.
No pyrometallurgical smelter can operate without some form of tapping system.
It is the one thing all smelters have in common. A meeting point of science,
technology and skill.
So let us talk about it.
The key interest areas to be covered in this symposium are all aspects of the
fundamentals, synthesis, analysis, design, monitoring, and control of metals,
materials, and metallurgical processes and phenomena.

The Lead – Zinc 2020 symposium builds on the successes of the original 1970
meeting, the subsequent conferences held in 1980, 1990, 2000 and 2010, the Zinc
– Lead symposia in Japan organized by MMIJ in 1995 and 2005, the Lead-Zinc
conference in Germany by GDMB in 2015, as well as the Canadian Lead – Zinc
conferences organized by MetSoc in 1998 and 2008. It will provide an
international forum for the lead and zinc processing industries bringing
together operators, engineers and researchers to exchange information about all
aspects of current processing technologies for primary and secondary lead and
zinc, as well as emerging technologies for both metals. The symposium scope
extends from process fundamentals to operational practices, and also includes
the important aspect of environmental issues. At the operations level,
comprehensive reviews of the major applications of both metals are outlined.
Emphasis will be placed on recent commercial developments with less energy
intensive technologies which are in harmony with environmental conservation. At
the research level, the emphasis is placed on the better understanding of
existing technologies and the development of new processing concepts.
Environmental concerns, associated with the processing of both metals, are
considered along with acceptable treatment and handling of by-products, wastes
and bleed streams by the industry. A highlight of the conference will be a
series of plenary lectures by industry leaders. Various social events are
scheduled, and these will allow informal discussions and networking among the
delegates. After the symposium, industrial tours are planned to various North
American lead and zinc processing operations.
Topics to be discussed at the symposium include:

blast furnace, QSL, KIVCET, SKS-RSKS and TSL, as well as pyrometallurgical
refining, electrorefining, slag fuming and new processes),
* Product applications and marketing (galvanization of steel, chemicals, ZnO,
lead-acid batteries) and new product development,
* Recycling technologies and product life cycle issues (e.g. electric arc
furnace dust treatment and direct de-zincing, secondary lead processing), and

Electrolytic processing is used commercially to recover and/or refine metals
including large–scale production of aluminum, copper, magnesium, nickel, and
zinc as well as, on a smaller scale, for recovery and refining of gold and
silver. There are also exciting opportunities to utilize electrometallurgy in
the production of titanium, lead, and other metals. Electrolytic processing of
metals faces common challenges that include energy utilization, chemistry,
productivity, and safety. To meet the present challenges in commercial
electrometallurgy, a variety of technological advances have been made. Similar
challenges will be faced in the future, requiring process improvements and
innovations.
