【摘要】 本文研究了 Ni48Mn3 3 Ga1 9合金添加微量的稀土元素 Tb后 ,对合金的马氏体相变、磁致应变性能及抗弯性能的影响 ,发现合金的马氏体相变温度、磁致应变值有所下降 ,而机械抗弯强度有显著提高。

【Abstract】 Effect of microamount addition of Tb on the martensitic transformation, the magnetic field induced strain and the bending strength of Ni 48Mn 33Ga 19 alloy was studied in this paper.The experimental results show that the martensitic transformation temperature and the magnetic field induced strains decreased, while the bending strength increased remarkably.
