Abstract
We review here the George-Baker model for the yield strength anomaly o f FeAl which is based on hardening by thermal vacancies at intermediat e temperatures and dislocation creep at high temperatures. Results of up-quenching and down-quenching experiments; which corroborate the vac ancy hardening mechanism, are discussed. Some implications of the mode l are compared with available experimental results. (C) 1998 Elsevier Science Limited. All rights reserved.
