Title: Modification of Al-Si-Cu-Ni Alloys for Potential Electrical Applications
Abstract:
The aim of this study is to develop new cast aluminum alloys for the production of potential electrical applications in electric vehicles and the power industry. These applications include rotor bars and stator winding coil in electric motors plus transmission lines in the power industry. They require high as-cast strength and electrical conductivity. A design of experiment (DOE) technique, Taguchi method, was used to develop high as-cast strength and electrical conductivity alloys with various element addition of Si, Cu, Ni and Sr. The optimal combination of chemical composition for maximizing the ultimate tensile strength (UTS), electrical conductivity () and yield strength (YS) was 6 wt.% Si, 3 wt.% Cu, 0.03 wt.% Sr and 0.5 wt.% Ni. The alloy with the optimal composition had an average UTS of 247.58 MPa, an average electrical conductivity is 38.01 %IACS, and an average yield strength of 143.47 MPa. The Sr modification of Si phase in the alloy resulted in the enhanced mechanical properties and electrical conductivity.
