Dy对多晶Ni52Mn24.7Ga23.3合金马氏体相变和磁感生应变的影响
Effect of Dy on Martensitic Transformation and Magnetic-Field-Induced Strain in Polycrystalline Ni52Mn24.7Ga23.3 Alloy
【摘要】 研究添加不同量的Dy对多晶Ni52Mn24.7Ga23.3的马氏体相变和磁性能的影响,发现合金的马氏体相变温度显著提高,并且随着Dy的增加,在一定的外应力的作用下合金的磁感生应变值增大,材料的抗弯性能也有着明显的提高。
【Abstract】 Martensitic transformation and magnetic properties of a crystalline alloy Ni52Mn24.7Ga23.3 with different addition amount of Dy was investigated.The results show that martensitic transformation temperature was increased,bending strength and magnetic-field-induced strain was increaced under the external stress.
