| James T. Staley Dr. James T. Staley,
Sr. re-cently retired after 35 years at Alcoa in R&D and operations. There
he deepened his experience in developing and applying heat treatments for
aluminum alloy products. He led teams which wrote the chapters on Metallurgy
of Heat Treatment and General Principles of Precipitation Hardening
in Aluminum: Properties and Physical Metallurgy and Heat Treatment
of Aluminum in an ASM International Metals Handbook. He continues
to teach the metallurgy of heat treatment to Alcoa employees. He was awarded
the James Douglas Gold Medal for distinguished achievement in nonferrous
metallurgy by AIME and is a Fellow of ASM Internationsl.

During the week of February 11–15, 2001, 2001
TMS Annual Meeting & Exhibition will take place in New Orleans, Louisiana.
The Hilton New
Orleans Riverside Hotel will be the headquarters hotel for the event. All
conference events, including registration, technical sessions, and the exhibition
will take place at the Ernest N. Morial Convention Center.
To register for a course, please use the secure
on-line registration form or download the registration form in portable
document format. All courses will be held at the Hilton
New Orleans Riverside Hotel the weekend prior to the meeting, Saturday and
Sunday, February 10-11, 2001.
Presented by: Murat Tiryakioglu, Western Kentucky
University, and James T. Staley, Consultant
Who Should Attend: This 2 day course is intended for metallurgists, engineers, and technicians employed in either research or operations at facilities where cast or wrought aluminum alloy products are heat treated. Operations both at producers and users will be covered.
Course Overview: The course combines theory with many practical examples.
Strengthening mechanisms in aluminum alloy products are first reviewed. Then
the general principles of precipitation hardening including phase diagrams are
discussed. This is followed by an overview of the metallurgy of heat treatment.
The hardening precipitates in the major alloys will be identified. A major element
of the course is a description of how to use simple kinetic equations to predict
effects of quenching and aging on properties. Graphical computer programs that
illustrate these points will be demonstrated.
Contents of the course include solution heat treatment of castings with emphasis
on homogenization and rounding of Si particles and effects of time and temperature.
Discussion of the important step of quenching will include quench sensitivity;
water quenching and geometry; and effects of quench on residual stress, distortion,
corrosion, strength, and fracture toughness. Examples will be taken from 3XX,
2XXX, 7XXX, and 6XXX alloys. A method of predicting the properties using a Time-Temperature-
Property C-Curve and a cooling curve will be described, and the difference between
T-T-P and C-C-P (Continuous Cooling Property) Curves will be explained. Interactions
between quenching and aging will also be covered. Examples of natural aging
and ef-fects of time and temperature of artificial aging will then be discussed.
Examples of the contrasting effects of cold work prior to aging 2XXX and 7XXX
alloy products will be shown and reasons for the behaviors discussed. Multi-step
aging treatments will also be discussed with emphasis on T7 aging of 7XXX alloy
products and low-high temperature ag-ing of Al-Si castings.
