For this purpose, complex plastometric tests of new grades of alloys were carried out to obtain experimental data on the deformation resistance value σp and maximum permissible plasticity Λр of these materials. The tests were carried out on a modern plastometric apparatus in a wide range of thermal mechanical conditions of deformation according to different forms of loading.
