Abstract
The quench of 150CrNiMo steel after austenitization in wide temperature range is done. Amount and tendency to deformational-induced transformation of retained austenite are investigated. Abrasive wear resistance and hardness tests were carried out. It is shown that wear resistance is in negative correlation with hardness. The decrease of hardness with elevation of austenitization temperature is caused by rise of retained austenite amount. At the same time the ability of metastable retained austenite to deformational-induced martensitic transformation leads to increase as of wear resistance so and microhardness of worn surface.
