Action of Magnesium on Carbide Spheroidization in Annealed Bearing Steel

Article Preview

Abstract:

The effect of magnesium on the morphology and composition of the carbide in annealed bearing steel was studied. The morphology of carbide was observed and statistical analysis was carried out. The results showed that the non-uniform distribution of carbides in bearing steel was obviously improved with increasing the content of magnesium. Segregation thermodynamics indicated that the segregation of magnesium to grain boundaries prevented element such as Cr, C from enriching on grain boundary, which was helpful for the reduction of network carbide precipitation. The chemical analysis results proved this viewpoint.
