Isothermal Transformation Diagrams of Austenite in Maraging Steel 08H15N5D2T at Overcooling

Abstract:

The diagrams of isothermal transformation based on kinetic curves R = (τ) for retained austenite in high-strength alloy low-carbon at overcooling have been built. It is shown that the temperature of quenching influences the stability at overcooling and resistance to isothermal transformation of austenite at sub-zero temperatures.
