Conclusions
The quenching of high-alloy chromium-manganese steels, which includes preheating in the intercritical (α+γ) temperature interval and subsequent short-term austenitizing, the latter eliminating homogenization of the γ-solid solution, increases the dispersity of the martensite and stabilizes the austenite.
In this case, the strength and plastic properties of the steels are improved as compared with normal quenching.
