研究和解决航空高温结构材料,是现代航空发展中所面临的关键性问题之一。现有的耐热合金不能满足日益发展的高速飞行的需要。因此,对改进现有材料,特别是发展新型的耐高温材料,成了当前急待解决的任务。本文根据国外发表的文献综述了:现代航空发展中所面临的高温材料问题及其解决途径;与高温材料发展有关的合金高温强化问题及发展与应用;现有钴基耐热合金的现状及其研究改进趋向与;发展高熔点金属及陶瓷、金属陶瓷等新材料领域中,研究工作的基本情况,存在困难,解决途径与发展趋向。
Studying and solving aviation high-temperature structural materials is one of the key issues in the development of modern aviation. The existing heat-resistant alloy can not meet the needs of the growing high-speed flight. Therefore, it is an urgent task to improve the existing materials, especially the development of new high temperature resistant materials. Based on the literature published abroad, this paper summarizes the problems of high temperature materials and their solutions in the development of modern aviation, the problem of high temperature strengthening and its application in the development of high temperature materials, the current situation of the existing cobalt base heat resistant alloys and their Researching the trend of improvement and the development of new materials such as refractory metals and ceramics and cermets, the basic situation of research, difficulties, solutions and development trends.
