In situstudy of the self-accommodating process during the martensitic transformation of a Cu-Zn-Al single crystal by synchrotron X-Ray topography—I. crystallographic study

The thermoelastic transformation of the CuZnAl shape memory alloy has been studied in situ and in real time by synchrotron X-ray topography. The white nature of the beam leads access to crystallographic relations between crystals in β and 9R phases. From our original method deduced from the Kajiwara theory the experimental and simulated orientations have been compared and the self-accommodating character of the transformation has been shown.
