Variation of α → γ Transformation Temperatures in Steel with Controlled Austenitic Transformation during Operation, Depending on Its Structural–Phase State
摘要
The critical temperatures of the α → γ transformation in 5G4N3Kh2M2FSTB die steel depending on its initial state (different levels of saturation of the solid solution) are determined. It is found that, at low rates of heating (2 K/min), the decrease in the level of saturation of the solid solution results in an increase in temperature AC1. An opposite effect is observed at higher rates of heating (10 K/min).
