“Calphad Thermodynamics”

Presented by:
Larry Kaufman, Lecturer/Consultant

About the topic:
Hume-Rothery’s “Atomic Theory for Students of Metallurgy” was an advanced text that introduced modern quantum mechanical ideas to undergraduates in the early 50’s. In 1966 Mr. Kaufman had the opportunity to spend a week in Geneva at the Battelle Conference on “Phase Stability in Metals and Alloys” with Hume-Rothery, Brewer, Zener, Friedel and Kubaschewski. Hume-Rothery invited him to review the subject for Volume 14 of Progress in Materials Science, published in 1969 which Hume-Rothery edited and they had an extensive 30-month discussion by mail covering many aspects of the Battelle Conference and Mr. Kaufman’s PMS paper until Hume-Rothery’s death in September 1968. Kubachewski’s NPL and Brunel conferences in July 1971 and the Munster Conference in 1972 set the stage for the birth of the “CALPHAD” method, Journal and Conferences which have grown and continue until today. At the TMS 2001 Annual Meeting in New Orleans, the Symposium on “Computational Thermodynamics and Materials Design” illustrated many cases where CALPHAD THERMODYNAMICS, affording the broadest description of the stability of stable, metastable and unstable phases over wide ranges of composition, temperature and pressure could be used in the description of commercially useful materials and processes. This discussion will make the connection between Hume-Rothery’s seminal work, the basis adopted in the development of the predictive CALPHAD method and the current status of the science of “Alloy Thermodynamics”. A number of unresolved problems and areas for research opportunities will be addressed.
