金属材料为了适应各自使用目的的要求,一直趋向于多元系合金方向发展,而且通过热处理和加工方法的配合达到了实用化目的。但是,由于在特性的提高和改善方面受限,而且难以同时兼备截然不同的两种以上的特性,故很难获得所需的性能优异的材料。为此,可使材料兼具不同优异特性的材料复合方法脱颖而出。从广义上来讲,通过 Metal materials in order to meet the requirements of the purpose of their use, has tended to tend toward the direction of the multi-alloy, and through the combination of heat treatment and processing methods to achieve practical purposes. However, since it is difficult to improve and improve the characteristics and it is difficult to combine two or more distinct characteristics at the same time, it is difficult to obtain the desired material with excellent properties. To this end, material composite methods that allow materials with different excellent characteristics to stand out. In a broad sense, passed
