金属学报

由TEM的电子衍射谱观察证实CuZnAl形状记忆合金中马氏体变态A和B之间实际上是二次孪晶关系,其孪生面(13 20 50)为A:C关系的孪生面(1 2 8)和A:D关系的孪生面(1 0 10)的线性组合。

A secondary twinning orientation relationship between A and B martensite variants in a CuZnAl shape memory alloy was confirmed under TEM observation.The twin plane, (50),is a linear combination of (8)and(1 0 10)planes,which are twin planes of A:C and A:D type pair respectively.
