The Al-Si-Cr-Co-Ni High Entropy Alloy (HEA) with low density (about 5.4 g/cm3) and excellent performance had significant potential in the lightweight engineering material field. To further research optimize system HEA, influences of element Cr on microstructures performances AlSi0.5CrxCo0.2Ni (in mole ratio, x = 1.0, 1.2, 1.4, 1.6, 1.8) HEAs were investigated. experiment results manifested that...

The aim of this research was to highlight how meritocracy can be adopted tap youth as a resource for development in Developing countries. This meritocratic perspective is based on the premise that one's talents are primarily derived from their inherent qualities (e.g., personality and general intelligence).
