Abstract

In the work on specific examples involving real copper-based alloys containing 14 weight %Al and 3 weight
%Mn, describes the results of a study of the process of restoring the shape of a material that was defomated
according to the three-point bending scheme. The studies were carried out by measuring changes in the
temperature dependence of the electrical resistance and deflection of the sample, as well as by obtaining
microelectronograms using an electron microscope. It is established that martensitic crystals that occur in
hardened samples have a high density of packing defects and thin twins formed on the (121) γ´ plane.
