Abstract
In this study, effect of modification treatment via Fe–Si–Mg–Ca–RE modifier on microstructure of ultrahigh carbon steel containing 1.5 wt% C was investigated. Microstructure characterization was performed by optical microscopy. It was found that as-cast proeutectoid carbide network tend to break after the modification treatment, and the carbides changed to discontinuous and spherical shape and uniformly distributed in matrix. Also, grain size, porosity and inclusions content decreased by modification treatment.
