摘要
Inconel 718合金中δ相数量与形貌的控制是保证产品性能的关键因素。介绍了近年来Inconel 718合金中δ相对其组织与疲劳性能影响的研究进展。综述了合金中δ相的形成与析出、溶解规律,δ相与热变形参数间的对应关系及δ相对疲劳性能的影响。
It is the key factor to ensure the properties of the product that the quantity and morphology of 3 phase in Inconel 718 alloy. The research progress in effect of δ phase on microstructure and fatigue property of Inconel 718 alloy are summarized. Three aspects, the formation, precipitation dissolution behavior of δ phase, relationship be tween δ phase and hot deformation parameters, effect of δ phase On the fatigue property, are introduced.
