金属基复合材料在汽车发动机和宇宙飞船等方面的实用化 ,关键在于开发能耐苛刻工作环境要求的材料。采用特殊方法制作的Ａｌ2 Ｏ3之类氧化物纤维与Ｎｉ Ａｌ系金属间化合物或镍基高温合金复合化 ,获得了高温强度特性优越的金属基复合材料。当前已开发成功了一系列制取这类材料
The key to the practical application of metal matrix composites in automotive engines and spacecraft lies in the development of materials that meet the demanding requirements of the work environment. Al 2 O 3 -based oxide fibers and Ni-Al-based intermetallic compounds or nickel-based superalloys produced by a special method are combined to obtain a metal matrix composite having excellent high-temperature strength properties. There have been a series of successful development of such materials
