鎂微合金化GH169的研究與發展

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

摘要: 系統地研究了鎂對GH169合金的綜合性能,特別是在高溫接近使用條件下力學行為的影響,從而提出在GH169合金中應控制合宜含鎂量的新要求.成為生產和發展具有我國特色的優質GH169合金的一個重要手段。

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).
