Abstract

The durability of materials realizing shape memory effect testifies that the accumulation of defects of a crystal structure in this process occurs more slowly in comparison with irreversible deformation. The attempts were undertaken to simulate process of generation of a field of stresses in process of martensite transformations, but they did not prove to be true by experimental data. In offered work the attempt of an experimental research of a residual field at a structural microlevel is undertaken. Meaning complex phase structure interfering to a choice of two orders reflection from family of planes or frequently even of two peaks from one phase, as a first approximation investigated root-mean-square (RMS) microstrains and coherent block sizes analyzing one diffraction peak. In case of necessity used also separation of the overlapped peaks of different phases.
