| 摘 要： | 铁磁性Heusler型合金Ni2MnGa是近年来开发的新型磁控制功能材料，但其马氏体相变温度通常远远低于室温，不利于实际应用。本文研究了多晶Ni48Mn33Ga19合金的马氏体相变特征，发现该合金的马氏体相变温度已提高到室温以上。在室温下，分别测量了不同条件下制备的试样的磁场诱发应变，提出了增大材料磁致应变的有效方法。

| Abstract: | Ferromagnetic Heusler alloy Ni 2MnGa has been developed as a new magnetic field control actuator material But the martensitic transformation temperature of Ni 2MnGa is usually quite lower than room temperature The martensitic transformation of a polycrystalline alloy Ni 48 Mn 33 Ga 19 was investigated The results show that its martensitic transformation temperature is higher than room temperature Moreover,the magnetic field induced strains of the samples,which were prepared by different methods,were measured at room temperature The effective ways to increase magnetic field induced strain of the material have been discussed |
