On some physical properties of nanostructured Cu-Pb alloy prepared by mechanical alloying

Cu-Pb alloys have no solubility in the whole solid state and their physical properties are very different from each other. In the present study, nanostructured Cu-Pb alloy powders were synthesized by the mechanical alloying process, and their nanostructural characteristics were evaluated in order to elucidate the relationship between structure and properties. By appropriate control of mechanical alloying process variables, the Pb solid solubility in Cu matrix was increased up to 10 wt.%. The monotectic temperature of Cu-Pb alloy was also decreased by decreasing the crystalline size. The relation between the structure and properties of this nanostructured Cu-Pb alloy is discussed on the basis of the experimental results. Copyright (C) 1996 Acta Metallurgica Inc.
