摘要: 用光学显微镜,透射电子显微镜及X射线衍射技术研究了粉末高温合金FGH95在热等静压及热等静压加热处理状态的显微组织。结果指出:在上述两种状态下试样中存在着γ'、MC、M23C6相,在原粉末颗粒边界发现有富A1和Zr的氧化物。Abstract: Microstructures of P/M superalloy FGH95 in the HIP'ed and HIP'ed plus heat treated condition are investigated with optical microscopy, TEM, and X-ray diffraction. The results show that r' MC,M23C6 phases are present in samples after both HIP'ed and HIP'ed plus heat treated condition.Al-rich and Zr-rich oxides are found at the primary particle boundaries.
