Effect of rare earth Ce on as-cast precipitates of Cu-containing low-temperature grain-oriented silicon steel

Abstract

Abstract: Effect of rare earth element Ce on the as-cast microstructure and precipitates of Cu-containing grain-oriented silicon steel was investigated by means of laser scanning confocal microscope and transmission electron microscope. The results show that rare earth element Ce can refine grains in the as-cast microstructure of the Cu-containing grain-oriented silicon steel. In addition, there are coarse (Cu,Mn)S+AlN composite precipitates and a small amount of separate precipitates including MnS and Cu₂S in the ingot cast without Ce addition. By adding Ce, the types of the as-cast precipitates do not change, while their amounts decrease significantly and their sizes increase somewhat.

Key words: grain-oriented silicon steel, precipitates, as-cast, rare earth Ce
