Abstract

Methods of the optical metallography, TEM, SEM- technique, X-ray analysis, tests for hardness and wear resistance, are resulted results of research and optimization of structure and properties facing materials with austenite-martensite structure and with various quantity of strengthening phases. The maintenance in facing material austenite 38% is shown, that, martensite 32% and strengthening phases of 30% provide the highest relative wear resistance  = 5.89 and hardness HRC 61.
