摘要
在普通黄铜中加入Fe、Mn和Si等元素后,可在基体中形成Mn_5Si_3或Fe_3Si颗粒相,从而可大幅度提高黄铜的强度和耐磨损性能.对这类黄铜进行淬火和回火处理,可改变显微组织中颗粒相的粒度、分布和致密度,从而可进一步改善材料的性能,尤其是当合理地控制回火温度和时间,使显微组织中出现少量α相时,可使材料的耐磨损性能达到最佳状态.
Additions of Fe,Mn and Si to binary brasses result in the formation of Mn_5Si_3 or Fe_3Si particles.The strength and wear resistance of brasses are increased significantly.Quenching and tempering of these brasses would change the particle size, distribution and density of particles so that the properties of brasses are further improved.Especially,when small amount of the α-phase exists in the microstructure of brasses,the wear resistance will be optimum if tempering temperature and time are well controlled.
