An analysis of mechanical and mechanic instabilities in Ni-Mn-Ga single crystals was carried out. Experimental stress-strain and magnetization versus field curves, measured for Ni2MnGa alloys were also compared with modeling results obtained using a statistical model. The results indicate that it is possible to evaluate the critical stress, which is necessary to overcome twin boundary pinning in a defined martensite structure.

Abstract
An analysis of mechanical and mechanic instabilities in Ni-Mn-Ga single crystals was carried out. Experimental stress-strain and magnetization versus field curves, measured for Ni2MnGa alloys were also compared with modeling results obtained using a statistical model. The results indicate that it is possible to evaluate the critical stress, which is necessary to overcome twin boundary pinning in a defined martensite structure.File in questo prodotto:
