近年来,为满足各种各样设计项目的要求,相继开发了高比强度材料、超耐热合金、耐火合金,纤维增强金属(FRM)等结构材料,高导磁率材料、半导体材料、非晶态材料、记忆合金等功能材料,以及同时具有一定功能和结构强度的各种复合材料等。并且,与此相应的许多新的加工方法也应运而生。 In recent years, in order to meet the requirements of various design projects, we have successively developed structural materials such as high specific strength materials, superalloys, refractory alloys, fiber reinforced metals (FRM), high permeability materials, semiconducting materials, State materials, memory alloys and other functional materials, as well as at the same time have a certain function and structural strength of various composite materials. And, corresponding to this many new processing methods also came into being.
