Abstract

Abstract

The stain-induced microstructural changes of Fe₃Al-based alloys during room temperature deformation and high temperature creep were investigated. The results illustrated the strain-induced disordering occured during room temperature deformation. Creep strain could induced two opposite processes, which are strain-induced disordering and creep recovery-induced reordering. These two opposite creep induced processes during creep result in reducing the influence of primary microstructure on the rupture life.
