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......
, and the transverse rupture strength increases. However, the slope values of K in Hall-Petch relationship are higher in WC-CoNiFe than those in WC-Co, indicating the high toughness of medium entropy alloy Co-Ni...-CoNiFe are smaller than those of WC-Co cemented carbides, indicating a high toughness of CoNiFe medium entropy alloy. Figure 8 Hall-Petch relationships of hardness and TRS in WC-CoNiFe and WC-Co......
