摘要
采用透射电镜（ＴＥＭ）研究了Ｎｉ４７Ｔｉ４４Ｔａ９合金中马氏体和β－Ｔａ相的形貌及精细组织。结果表明，马氏体主要呈细板条状和群团状两种形貌，其亚结构为孪晶；β－Ｔａ相粒子呈椭球状分布于ＴｉＮｉ基体中，其内部存在大量位错和孪晶。
The morphology and structures of martensite and β-Ta phase in the Ni47Ti44Ta9 shape memory alloy were investigetal by means of transmission electron microscopy(TEM).The results show that the martensites are fine plate and cluster in shape at room temperature,the internal defects in the Ni47Ti44Ta9 martensite are twins, and the β-Ta particles are elliptical in shape having a lot of dislocations and twins inside.
