The results show that Bi and Sb are mainly distributed on grains and grainboundaries, and Bi on grainboundaries there are mainly simple substance Bi particles, Sb in grains are intermetallics containing stibium. The tensile strength, yield strength, elongation and variation of area of halfhard brass containing bismuth and stibium are 478.9 MPa, 295 MPa, 15.1% and 29.3% respectively. Corresponding to HPb59-1, the cutting property of brass containing bismuth and stibium is excellent. The brass containing bismuth and stibium shows excellent dezincification corrosion resistance, and the depth is 323 μm.
结果表明:添加的Bi和Sb主要以单质或化合物方式存在于无铅黄铜的相内和相界处,Bi以单质颗粒存在于相界处,Sb以化合物形式存在于相内,这对提高合金切削性能有利;添加Bi和Sb黄铜的抗拉强度为478.9 MPa,伸长率为15.1%,断面收缩率为29.3%,屈服强度大约为295 MPa;添加Bi和Sb黄铜的切削性能比HPb59-1铅黄铜的优,合金的脱锌腐蚀性能良好,脱锌层厚度约为323 μm。
