Microstructures of P/M Superalloy FGH95 in the HIP' ed and HIP'ed Plus Heat Treated Condition
-
摘要: 用光學顯微鏡,透射電子顯微鏡及X射線衍射技術研究了粉末高溫合金FGH95在熱等靜壓及熱等靜壓加熱處理狀態的顯微組織。結果指出:在上述兩種狀態下試樣中存在著γ'、MC、M23C6相,在原粉末顆粒邊界發現有富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.
