Abstract
In this study, a lightweight Al24.2Si3.25Cu24.2Ni24.2Ti24.2 high-entropy alloy was developed by sonication blending of the pure elements followed by the high-temperature sintering in the nitrogen gas environment. Microstructural characterization of the sintered alloy showed a fair dispersion of the elemental particles in the matrix during the blending process and the absorption of nitrogen, which led to the formation of multiple intermetallic compounds, including the nitrides, during the sintering process. Mechanical characterization of the sintered alloy revealed significantly high microhardness values with relatively lower compressive strength in Al24.2Si3.25Cu24.2Ni24.2Ti24.2 alloy.

Key words
