摘要：
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 Ti50Ni30Cu20 alloy. Consequently, the second B19-B19 ' transformation was found with M-s = 192 K. The lattice parameters of both martensites were also determined as a function of temperature.
