摘　　要：Inconel 713C合金是γ′相沉淀强化型镍基铸造高温合金。该合金因其良好的综合性能，目前广泛应用于各个工业领域，特别是航空航天、船舶、汽车、石油化工等。该合金在铸造生产中容易出现冶金缺陷，如疏松和气孔，这些均严重影响着合金的使用可靠性和铸件的成品率。近年来，国内外对该合金的凝固过程、组织和性能方面进行了大量的研究，本文综述了近年来针对Inconel 713C合金开展的一些研究成果。Inconel 713C alloy is the γ′ phase precipitation hardening nickel-base superalloy. Because of its good performance, this alloy is now widely used in various industrial fields, especially in aerospace, shipbuilding, automobiles, petrochemicals and so on. But casting production prone to defects, such as metallurgic porosity and microstructure loose, which are a serious impact on the reliability and castings yield of the alloy. In recent years, the solidification process, organization and performance of this alloy have been researched in the world-wide. This paper summarizes the results of some recent studies for the Inconel 713C alloy.
