Abstract
The influence of thermal cycling on the characteristics of the martensitic transformation in Ni45.4Mn40.9In13.7 alloy was investigated. It was shown that after 1000 repeated thermal cycles trough temperature interval of the martensitic transformation, application of magnetic field of 1.1 T resulted in higher transformation temperatures shift of 10 K/T compared to 7 K/T before cycling. On the other hand, the measurements display a steady increase of electric resistivity with the number of cycles that along with decrease of the transformation latent heat indicate the phase hardening. The means to prevent functional degradation of magnetocaloric materials due to phase hardening are suggested.
