Influence of Carbon Content and Solidification Condition on Incipient Melting of DS Superalloy MAR-M200+2Hf郑运荣,王罗宝,李成功摘 要:<正> Hf lowers the incipient melting temperatureof superalloy. As carbon content in Hf-bearingalloy decreases, the incipient melting temperaturedrops furthey. PD ingots have stronger tendencyto incipient melting than HRS ones......

, it is very important to study the microstructures of the composite material synthesized under the various conditions. Under equilibrium solidification condition, Nb-18.7%Si(mole fraction) alloy contains a stable Nb+Nb5Si3 micro- structure. This could be changed through the variation of the solidification condition. Fig.2 shows the microstructure of the suction-cast Nb-18.7%Si(mole fraction......
