The Effect of Order on the Martensitic Transformation in Fe3Pt

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

The lattice parameter and Curie temperature of austenite in Fe3Pt increase sharply on ordering for times up to 2 hr at 650° C. These effects, together with a rapid decrease in the martensitic transformation temperatures, are interpreted in terms of increased short-range order. The onset of thermoelastic reversibility of the martensitic transformation is associated with the development of a significant volume fraction of long-range ordered domains.
