镁微合金化GH169的研究与发展

Research and Development of GH169 Superailoy with Micro-Alloying of Magnesium

摘要: 系统地研究了镁对GH169合金的综合性能,特别是在高温接近使用条件下力学行为的影响,从而提出在GH169合金中应控制合宜含镁量的新要求.成为生产和发展具有我国特色的优质GH169合金的一个重要手段。

Abstract: Magnesium effect on mechanical properties of GH169 superalloy especially at high temperature service condition has been studied in a wide range. A proper content of Mg should be controlled to meet a new requirement, which is important for developing high quality GH169 (INCONEL718).
