Entropy change linked to the martensitic transformation inmetamagnetic shape memory alloys

Original language description

The magnetic contribution to the martensitic transformation entropy change plays a crucial role in the transition properties of metamagnetic shape memory alloys. This contribution leads to a common dependence of the total entropy change at the structuraltransformation, ?Str, on the normalized temperature difference ?trA=(TAC-Ttr)/TAC (where TAC is the Curie temperature of the austenitic phase and Ttr is the transformation temperature) whose main feature is a decrease in ?Str with increasing ?trA. A phenomenological model based on a Bragg?Williams approximation has been proposed to describe the observed behaviour in terms of the evolution of the magnetic contribution to the total entropy change.
