The mechanism of plastic deformation of a MAX phase based on Ti–Al–C elements is investigated in the temperature range 1000–1200 °C. It is shown that at temperatures about 1000 °C the determining mass transport mechanism is the grain-boundary

In this study, experimental data have been obtained which reveal taking place of complex physical processes under conditions of the structural superplasticity not only in the grain boundary, as it is commonly believed, but also in the grain body. It
