Enhancing the structure and mechanical properties of Cu-3Si-Al ternary alloy by addition of aluminium
Description
Abstract: The enhancement of the structure and mechanical properties of a Cu-3Si-Al ternary alloy by the addition of aluminum was achieved through careful alloy design and processing techniques. In this study, aluminium was introduced into the Cu-3Si binary alloy in concentrations of 0.1-5wt% and fabricated using stir-casting technique. The microstructural changes in the alloy were investigated using an optical metallurgical microscope (OM). The OM results show increased solid solution regions and finer grains in the Cu-3Si alloy doped with aluminium compared to the parent alloy (Cu-Si), leading to improvements of ultimate tensile strength, percentage elongation, and hardness, with maximum values of 314 MPa, 28%, and 278 BHN, respectively.
