Abstract

Abstract

The influence of rare earth modifier on nonmetallic inclusion morphology and size distribution of 1500 MPa grade hot stamping steel were investigated by optical microscope and scanning electron microscope. And the microstructure and plastic property of resulted steel at room temperature were compared. The results showed that macro segregation disappeared in the rare earth modifier treated steel. After rare earth modifier treatment, the size of D-type particle inclusion decreased obviously, however, the density of inclusion kept increasing. With the rare earth modifier treatment, the microstructure was refined apparently and the plastic property at room temperature was improved.
