Abstract
In this study, the effects of nickel and copper on the mechanical and thermal properties of Al-Si alloys were investigated, for different alloy compositions. Thermodynamic calculations were carried out to predict the alloys’ solidification behavior (solidification temperature, solid fraction and physical properties (density, thermal conductivity, elastic modulus, bulk modulus)). The..... More

Abstract
High entropy alloys (HEAs) are a relatively new class of metallic materials. HEAs lead to high mixing entropy and the formation of a simple solid solution rather than intermediate phases. This might be explained by the fact that the configurational entropy outweighs the enthalpy of formation of intermetallic compounds. Meanwhile,..... More

Abstract
In the present study, we systematically investigated the effect of entropy of mixing (ΔS_mix) on the mechanical and thermal properties of single phase FCC solid solutions with multi-principal elements. An increase in ΔS_mix led to an increase in micro-hardness and a decrease in thermal conductivity (κ) due to severe lattice..... More
