【摘要】 变形高温合金是指通过铸造-变形工艺生产的高温合金,包括盘、板、棒、丝、带、管等产品,该类产品广泛用于航空、航天、能源、石化、核电等工业领域。本文介绍了国内变形高温合金近10年的最新进展,分别从变形高温合金的制备工艺流程,GH4169G、GH4169D、GH4065、GH4068等新合金的研制,以及FGH4096的变形化、NGH5011的氮化、In718合金的3D打印等新技术3个方面展开论述。更多还原

【Abstract】 Wrought superalloys are high temperature alloys produced by casting-forging-hot rollingcold drawing, including disc, plate, bar, wire, tape, pipe etc. These products are widely used in aviation,aerospace, energy, petrochemical, nuclear power and other industrial fields. In this paper, domestic progress of wrought superalloys in recent ten years was reviewed, including advances in fabrication process,research in new alloys(GH4169G, GH4169D, GH4065 and GH4068 alloy et al.) and new techniques(deforming of FGH4096 alloy, nitriding of NGH5011 alloy and 3D printing of In718 alloy et al.).更多还原
