通过原位电子显微镜观察，确定该合金中的晶格不变剪切为(001)B19‘复合孪晶。实验观察到B2母相与B19‘马氏体之间贝恩变形的晶格对应关系为：[010]B19’-[011]B2，[100]B19‘-[100]B2和[001]B19’-[01̄1]B2。
The lattice invariant shear in the present alloy was determined as being (001)B19′ compound twins by in situ transmission electron microscope (TEM) observations. The lattice correspondence of the Bain distortion between the B2 parent phase and the B19′ martensite was experimentally observed and determined as being [010]B19′-[011]B2, [100]B19′-[100]B2 and [001]B19′-[01̄1]B2.
