摘要
研究多晶合金Ni52.5Mn23.5Ga24的马氏体相变特征和磁感生应变性能。
Martensitic transformation and magnetic-field-induced strain were investigated in a polycrystalline alloy Ni_(52.5)Mn_(23.5)Ga_(24).The influences of rare earth Tb on the martensitic transformation and magnetic properties of Ni_(52.5)Mn_(23.5)Ga_(24) alloy was analyzed.The experimental results show that martensitic transformation temperature is increased to above room temperure,temperature hysteresis is decreased and magnetic-fiele-induced strain is enhanced under the association of external stress by microamount addition of Tb.
