Abstract

The characteristics of alloys with the shape memory effect are presented. The physical nature of the process of a change in the shape is examined. The structure of the high-manganese alloys of Mn-Cu system with shape memory is described. The role of neutron analysis in studies of structural transformations in Mn-Cu alloys is shown. On the basis of the results of measuring the temperature dependences of internal friction in the magnetic fields of different magnetizing force, the presence of the magnetic contribution to the pretransition anomalies in Mn-Cu alloys is assumed. The prospects of applying the neutron analysis in studies of alloys with the shape memory generally and, in particularly, in the Mn-Cu alloys are shown.
