Abstract
Considering the slip shear system as the lattice invariant system, simple analytical solutions for the habit orientation, amount and magnitude of the lattice invariant shear and the orientation relationship between austenitic and martensitic phases were derived for the martensitic transformation face centered cubic (fcc) to body centered cubic (bcc) by using the infinitesimal deformation (ID) approach. The results of the present study were numerically compared with experimental results and the BowlesMackenzie (B-M) theory.

En considérant le système de glissement par cisaillement comme étant le système invariant du réseau, on a dérivé des solutions analytiques simples pour l'orientation de la forme cristalline, pour la quantité et la grandeur du cisaillement invariant du réseau et pour la relation d'orientation entre les phases austénitiques et martensitiques de la transformation martensitique cubique à faces centrées (c.f.c.) à cubique centrée (c.c.) en utilisant l'approche de la déformation infinitésimale (DI). On a comparé numériquement les résultats de la présente étude avec les résultats expérimentaux et avec la théorie de Bowles-Mackenzie (B-M).
