摘要
实验结果表明，对ＰＲＥＰ法ＦＧＨ９５合金粉末进行预热处理。可以使亚稳碳化物（ＭＣ’）向稳定型的ＭＣ、Ｍ２３Ｃ６、Ｍ６Ｃ型碳化物转变，明显改变碳化物的分布状态，有效地抑制ＰＰＢ的形成。
In this paper,the various temperature (950～1150℃) pre heat treatment was used for the PREP(Plasma Rotating Electron Pole)FGH95 powder particles.The results show that during pre heat treatment,the nonequilibrium carbides(MC') can be transformed into stable carbides (MC、M 23 C 6、M 6C),and the appropriate control of this transformation may suppress the formation of detrimental PPB(Previous Powder partical Boundaries) carbides.
