Abstract

Considering the concrete slip system as a lattice invariant shear one, the orientation relationship between austenite and martensite and the analytical solutions for the habitus orientation, amount of lattice invariant deformation, and magnitude of the total shape deformation have been derived using rigorous version of the infinitesimal deformation (ID) approach for a description of the fcc to bcc martensitic transformation observed in an iron-platinum alloy with 24.5 at % Pt. The results of the present study are numerically compared with those obtained both in experiment and within the infinitesimal approach and a phenomenological theory of Bowles and Mackenzie (BM).
