Effect of Homogenizing on Microstructure of ZG80Cr2MnMoSi Steel

ZG80Cr2MnMoSi steel is a multicomponent alloy steel for use with wear-resistant liner.The segregation of chemical composition and microstructure is extremely easy to occur in the casting due to high content of carbon and alloying elements.Homogenizing is commonly adopted in practice to weaken the harmful effect of segregation on casting property.The effect of homogenizing on the microstructure,carbide type and grain size as well as the factors affecting grain refining were investigated with respect to ZG80Cr2MnMoSi steel.The results show that:(a) re-dissolving te
