Effect of temperature and texture on the reorientation of martensite variants in NiTi shape memory alloys
TLDR
In this paper, the effect of texture and temperature on reorientation of martensite variants was investigated, and the authors used a thermodynamic approach involving the elastic strain energy associated with the growth of reoriented martensites to rationalize these temperature dependencies.About:

Criterion for the action of applied stress in the martensitic transformation
J.R. Patel,Morris Cohen +1 more
TL;DR: In this article, the martensitic reaction is treated as a strain transformation with shear and dilatational displacements, respectively parallel and normal to the habit plane, and the resulting effect on the temperature is calculated from the mechanical work done on or by the transforming region as the resolved shear, and normal components of the applied stress are carried through the corresponding transformation strains.
