摘要
通过对ＨＫ４０、ＨＰ４５和ＺＧ４Ｃｒ２５Ｎｉ３５ＷＮｂ３种耐热钢高温力学性能的测试和各种状态下显微组织的观察分析，比较了其性能的优劣，并探讨了合金元素镍、钨及铌的作用。
By measuring the high temperature mechanical properties and analyzing the microstructures of three kinds of heat resistant steels (HK40, HP45 and ZG4Cr25Ni35WNb), their properties are compared correspondingly and the effects of alloying elements (Ni, W and Nb) are studied.
