铁磁形状记忆合金NiMnGa相界面运动的能量和热滞后
Energy of phase boundary motion and thermal hysteresis in Ferromagnetic NiMnGa shape -memory alloys
摘要
Abstract
Based on the thermo - dynamical theory and some experimental data, the relevant energy contributions related to the thermoelastic martensitic transformation for three off - stoichiometrie NiMnGa single crystals with the transformation temperature below, near and above room temperature, respectively, were calculated, and their influence to the transformation behavior was discussed. The results identify further that for a completely thermoelastic martensitic transformation, the slope of the transformation loop results from the elastic strain energy, and the thermal hysteresis comes from the friction of interfacial motion.关键词
