Abstract

Abstract

A Fe₃Al intermetallic compound with high room temperature ductility has been obtained by means of combination of proper alloying addition and hot deformation. The relationship between properties and fractography was investigated. It was found that the fracture model of the alloys became a mired intergranuar-cleavage model while the Fe₃Al containing no Cr showed pure cleavage one. The improvement of room ductility can be attributed to the increase of cleavage strength.
