一、前言 根据弥散强化理论,利用微细的第2相在钢中均匀弥散分布能够使钢的性能强化。但是传统的做法或者是用复杂的热处理使弥散强化相析出,或者是用粉末法来生产的。日本早稻田大学理工学部金属工学科长谷川正义与竹下一彦两人通过大量的实验发展了将固体氧化物或硫化物粉末从外部强制地添加剩铜水中,使之均匀弥散,从而达到强化的目的,称之为喷射弥散法。
First, according to the theory of dispersion strengthening, the use of fine second phase in the steel uniform dispersion can make the steel performance enhancement. However, the traditional method is to use complicated heat treatment to disperse the dispersed phase or to produce it by the powder method. Japan Waseda University, Faculty of Science and Engineering Metalworking Hasegawa justice and Takeshi Takehiko two through a large number of experiments developed solid oxide or sulfide powder from the outside to force the remaining copper water, so that the uniform dispersion, so as to achieve the purpose of strengthening, said that the purpose of strengthening, said The jet dispersion method.
