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. The addition of Fe, Mn and Si to ordinary brass can form Mn5Si3 or Fe3Si particles phase in the matrix, which can greatly improve the strength and wear resistance of the brass. Fire treatment can change the grain size, distribution and density of the microstructure, which can further improve the material properties, especially when the tempering temperature and time are reasonably controlled so that a small amount of α phase appears in the microstructure, Material wear resistance to achieve the best condition.
