Abstract:
We present the results of experimental studies of the return of Ni–Fe–Ga–Co and Cu–Al–Ni single crystals to the initial form at the macro- and microlevels after their deformation by compression and subsequent restorative heating. It is found that the geometric dimensions of the sample are reproduced with high accuracy (up to 20 $\mu$m). The microrelief appearing on the initially polished surface during crystal compression (the arithmetic mean profile deviation $R _ a\approx$ 0.25–0.75 $\mu$m, the average spacing of local protrusions of the profile S $\approx$ 0.027–0.11 mm) is not removed by subsequent heating and remains with further multiple repetition of deformation–restoration cycles.
