Microstructure, impact energy, density, and electrical properties of Cu-3Si alloy system doped with molybdenum

Abstract: The microstructure, impact energy, density, and electrical properties of Cu-3Si alloy system doped with molybdenum is investigated in this study. The influence of molybdenum contents on the surface morphology, physical, and electrical properties of Cu-3Si-xMo (x: 0.1-5 wt%) alloys was explored. The alloy compositions were designed using response surface optimal design (RSOD), melt, and cast using stir-casting technique. The fabricated Cu-3Si and Cu-3Si-xMo alloys were machined to required dimensions for impact energy, density, electrical resistivity, and conductivity. The microstructures of the developed alloys were analyzed using optical metallurgical microscope (OM). Results of the study showed that the Cu-3Si-Mo ternary alloy demonstrated excellent impact energy and density compared with the parent alloy. The Mo-doped Cu-Si alloy recorded lower electrical conductivity, indicating increased solid solution of molybdenum in the copper matrix as revealed by the microstructural images.The impact energy, density, and electrical properties of Cu-3Si-Mo alloy system decreased with increasing concentrations of molybdenum.
