✦ Synopsis

The superelastic stress-strain loops indicating complex temperature-time evolution of the single crystalline ferromagnetic shape memory Ni 49.4 Mn 27.7 Ga 22.9 alloy which undergoes the austenite-martensite transformation (MT) have been experimentally studied. A model of transformation behaviour based on the statistical description of martensite nucleation events is developed and used for the theoretical description and analysis of experimental data in compression tests.

Ni-Mn-Ga ferromagnetic shape memory alloys (FSMA) appear to be very promising active materials because they exhibit giant and fast strains. In this paper, a study of the martensitic transformation is proposed. The pseudoelastic behaviour under pure compression of a Ni 49.7 Mn 27.7 Ga 22.9 single cry

The magnetic shape memory phenomenon represents two effects-the magnetic-field-induced strain and the magnetic-field-assisted superelasticity. These are accompanied by large magnetization changes due to anisotropic magnetic properties of the martensite twin variants. Simultaneous measurements of str
