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......

(b)) embedded into the eutectic structures were also observed. EDS analysis results(Table 2) show that the coarse particles contain more Cu and Fe. Its composition is close to stoichiometric Al7Cu2Fe... ℃. Copper content has a great influence on the evolution of the eutectic. The coarse phases dissolve slowly in alloy with higher copper content.

observations. However, the eutectic alloy fractures transgranularly. Its fracture surface gives a layered tearing and cleavage appearance (Fig.9(b)) as opposed to the sharp faceted appearance in the NiAl-0.3Ru, as a result of the grain boundary decohesion. Moreover, the compressive fracture behavior of the eutectic alloy indicates predominant debonding along the b/Cr(Mo) interface at room temperature......
