Effects of Mo and Ti Additions on The High Temperature Compressive Properties of Iron Aluminides Near Fe3Al

Abstract

AbstractHot compression testing has been used to examine the effects of Mo and Ti additions on the yield strength and rate of work hardening for cast alloys near Fe3Al. A few powder processed materials have also been studied. Significant improvements in high temperature compressive properties on alloying have been related to increases in the DO3→B2 transition temperature and the associated changes in the nature of the dislocations involved in the deformation processes.
