耐热合金

日本在开发耐热钢的同时,进行了耐热合金的开发。为了提高耐热性,在合金中添加了Cr、Ti、Al、Nb等元素。根据强化机制,耐热合金可分为固溶强化型耐热合金和析出强化型耐热合金。代表性的固溶强化型耐热合金有NCF600、601、609(相当于Inconel Alloy 600、601、609),代表性的析出强化型耐热合金有NCF718、750(相当于Inconel Alloy 718、X750)和NCF800H(相当于Inconel Alloy 800H)。固溶强化型耐热合金进行时效处理,强度、硬度也不升高,所以高温强度不高,因此,与用于要求高温强度的结构件相比,更适合用于包括高温环境等腐蚀环境下要求耐久性的部件。析出强化型耐热合金中含有Al、Ti等元素,与SUH600一样,析出γ相,提高了合金的强度和硬度,因此,析出强化型耐热合金适用于弹簧、螺栓、发动机部件等要求高温强度的零部件。
