There are mainly five unsolved problems in the physical metallurgy field of Ti-Ni shape memory alloys as follows ; Morphology and crystallography of self-accommodation in B19' martensite, interface structure of <011>_<B19>, type II twin, crystallography of anti-phase like structure in B19' martensite, mechanism of multistage martensitic transformation in aged Ti-Ni alloys and relation between anomalous ductility and grain boundary structure of B2 parent phase. These problems have been investigated by novel electron microscopy techniques. One of notable results is systematization of self-accommodation as clustering of habi plane variants around <111>_<B2>.

Ti-Ni形状记忆合金的物理冶金领域主要有五个尚未解决的问题：B_（19）′马氏体自适应的形态学和晶体学，_（19）′马氏体的界面结构<011><B19>，Ⅱ型孪晶，B_（19）′马氏体反类相结构的晶体学，时效Ti-10马氏体多级相变机制Ni合金的异常塑性与B2母相晶界结构的关系。这些问题已被调查的新的电子显微镜技术。一个值得注意的结果是系统化的自适应作为集群的双平面变量周围<111>_<B2>。
