B_2型FeAl金属间化合物的制备及性能研究进展
Research advances in preparation and properties of FeAl (B_2) intermetallics
摘要
Abstract
The research advances in preparation and properties of FeAl (B_2) intermetallics were reviewed. Casting and powder metallurgy are major methods for FeAl preparation. Effective toughening of FeAl can be achieved by alloying, gain-size refinement, heat treatment and incorporating into composites. Alloying also helps to increase the high temperature strength and creep resistance by introducing secondary-phase particles for precipitation hardening and dispersion strengthening, and the service temperature of FeAl is expected to be above 700℃.关键词
