采用强同步辐射束进行直接 X 射线衍射实验，以确认固溶处理的 Ti50Ni30Cu20 合金中是否发生连续的 B2-B19-B19' 转变。因此，第二个 B19-B19' 转换被发现，Ms=192K。两种马氏体的晶格参数也被确定为温度的函数。
Direct X-ray diffraction experiments with an intense synchrotron radiation beam were carried out, to confirm whether or not the successive B2–B19–B19′ transformation occurs in a solution-treated Ti50Ni30Cu20alloy. Consequently, the second B19–B19′ transformation was found with Ms=192K. The lattice parameters of both martensites were also determined as a function of temperature.
