Abstract

Features of the microstructure formation in steel 30Cr2MnSiNi2WMo (VL-1) are studied with various heat treatment regimes: stepwise quenching at temperature below Ms (quenching and partitioning), and isothermal quenching for bainite. It is shown that the calculated optimum temperature of stepwise quenching does not provide the predicted amount of stable retained austenite in the test steel microstructure. Mechanical properties of steel 30Cr2MnSiNi2WMo after implementation of stepwise and isothermal quenching are determined. It is established that after isothermal heat treatment the steel studied exhibits reduced viscoplastic properties compared with a condition after bulk hardening and tempering.
