Abstract

The change in morphology and substructure of α′ martensite with a volume change accompanying austenite (fcc) to martensite (bcc) transformation was studied using various Fe-Ni-Co alloys. The volume change accompanying martensitic transformation was decreased by the Invar effect of austenite with Co addition to the Fe-Ni binary alloys. In Fe-28Ni-20Co and Fe-24Ni-30Co (mass%) alloys, small and negative volume changes were established (-0.30% and -0.39%, respectively). With a decrease in volume change, the transition temperature of martensite morphology from lenticular to lath increases. The dislocation densities in martensite and austenite decrease as the volume change approaches zero.
