摘      要：Three different bismuth-lead systems namely, Wood＇s alloy （Bi50Pb25Sn12.5Cd12.5）, Newton＇s alloy （Bi50Pb31.2Sn18.8） and Rose＇s alloy （B50Pb28Sn22）, with one used as fusible alloys were quenched from melt by melt spinning technique. Thermal analysis, structure and mechanical properties of all alloys have been studied and analyzed. From X-ray diffraction analysis, an intermetallic compound phase, designated Pb7Bi3 is detected. The formation of an intermetallic compound phase causes a pronounced increase in the electrical resistivity. The Wood＇s alloy containing-cadmium exhibits mechanical properties superior to both the Newton＇s and Rose＇s alloys. The presence of cadmium in Wood＇s alloy decreases its melting point. Wood＇s alloy has better properties, which make it useful in various applications such as in protection shields for radiotherapy, locking of mechanical devices and welding at low temperature.
