Effect of Heating Rate on Austenization Temperature of 20MnSi Steel
The influences of heating rate on austenization temperature of 20MnSi steel were systematically explored by DIL805A/D dilatometer.The results show that the heating rate has a significant effect on Ac1 and Ac3.Ac1 increases with the increase of heating rate,the temperature range needed for austenization decreases,the rate of forming austenite increases.
