摘要
采用工频感应炉熔炼,半连续铸造+热挤压的方法生产铋黄铜棒,并分析了其显微组织,测定了力学性能和切削加工性。研究结果表明,采用半连续铸造+热挤压的方法生产出的铋黄铜棒显微组织由α相、β相和少量单质铋相组成,其力学性能和切削加工性能与HPb59-1黄铜相当,完全可以代替HPb59-1黄铜,从而有利于环境保护。
Bi-brass bars were produced by the combining manner of semi-continuous cast and heat extrusion, alloy was melted in induction furnace with frequency 50Hz.The microstructure of the Bi-brass was characterized by scanning electronic microscopy （SEM） with spectrometer and X-ray diffraction. Its mechanical properties was measured by the tensile test, and cutting performance was investigated by turning. The result shows that the process can be used to produce Bi-brass bars of high guality, whose microstructure is composed of α,β and Bi phase. The Bi-brass is compared with the HPb59-1 brass for the mechanical property and the cutting performance .It is possible that Bi-brass replaces the HPb59-1 brass. So the environmental pollution resulted from Pb will be prevented.
