of Mechanical Engineering, Tsinghua University, Beijing 100084, China) Abstract:The phosphide eutectic formation process in high purity Fe-4.6%C alloy, in which 0.02%~1.0%P was added, was studied with DTA, SEM and EDS, and the effect of cerium on the morphology of phosphide eutectic in the ternary Fe-C-P alloy was also investigated. The results show that the ternary phosphide eutectic......
