Hume-Rothery Award Lecture

“Entropies of Formation and Mixing in Alloys”

Date and Time: Monday, March 13
Location: Henry B. Gonzalez Convention Center
Hosted by: W. Alan Oates, University of Salford, UK

• Examples in which entropy plays a major role in determining the relative stability of phases in a system at high temperatures
• Methods used for estimating the magnitude of the contributions to formation/mixing entropies
• Models of value in the calculation of formation/mixing entropies for real multi-component alloys and of value in the calculation of phase diagrams for multi-component, multi-phase systems
• The value of the cluster/site approximation for describing the configurational contributions in multi-component, multi-phase systems, and recent developments in its application
• Methods suitable for the estimation of the magnitude of other contributions to formation/mixing entropies

SPEAKER

W. ALAN OATES Univ. of Salford UNITED KINGDOM

W. Alan Oates is the Honorary Visiting Professor at the Institute for Materials at the University of Salford in the United Kingdom, and has been a Fellow at the Institute of Metals, Mining and Materials in London since 1978.

Oates’ interests recently are in developing a higher order approximation which is suitable for multi-component alloys and in the thermodynamic modeling of intermetallic compounds.
