摘　　要：通过光学金相显微镜、扫描电镜及能谱分析、硬度测定,系统地研究了高强度耐磨铝黄铜合金(KK5)铸件中出现的大块状硬质点,分析了该硬质点产生的根源,并提出了相应的预防措施,经过生产实际验证,取得了良好的效果。Hard spots in high strength and wear resistant aluminum brass components were investigated systematically by optical microscope,scanning electron microscope and EDS,micro-hardness testing. Origination of the hard spots in the aluminum brass parts was described,and countermeasures were presented.

关 键 词：铝黄铜 硬质点 高强耐磨
