Abstract

The martensite structure of the Ni47Mn42In11 alloy has been studied, and crystallographic peculiarities of the structure realized after ten cyclic forward and reverse phase transformations have been shown. Each cycle includes the heating to a temperature corresponding to the existence of austenite and subsequent cooling to cryogenic temperatures. It was found that (107)-twinned martensite crystals can contact not only on the (10\(\bar 7\) ) plane, which, being the symmetry axis for the crystals, is not among the close-packed planes, but also on the (12\(\bar 7\) ) plane, which is among close packed planes but is not the symmetry axis.
