【 摘 要 】

The technique of thermomechanical treatment of high manganese steel under higherature plastic deformation of cylindrical specimens with various degrees of reduction is presented. The experimental data on the wear of samples on granite and electrocorundum show that the use of the thermomechanical treatment method can significantly increase the abrasive wear resistance of high manganese steel by up to 50%, and the method itself can be recommended for the introduction into the technology of manufacturing wear parts of ore mining and processing equipment in order to increase their service life.
