Abstract
In this paper, the chemical compositions of lead alloy made as a cable protection pipe were analyzed by using ICP-MS technique. The microstructures were observed by using optical microscope and scanning electron microscope. Experimental results indicated that segregation of doped elements coppor and antimony exist in the lead alloy pipe. Twin has been observed inside the grain of the cable protection pipe. Fine precipitates of Cu2Sb were observed in the grain and grain boundary.
