A low-density, nanocrystalline high-entropy alloy, Al20Li20Mg10Sc20Ti30 was produced by mechanical alloying. It formed a single-phase fcc structure during ball milling and transformed to hcp upon annealing. The alloy has an estimated strength-to-weight ratio that is significantly higher than other alloys comparable ceramics. High hardness retained after
Spin-driven ordering of Cr in an equiatomic fcc NiFeCrCo high entropy alloy (HEA) was predicted by first-principles calculations. Ordering is driven the reduction energy realized surrounding anti-ferromagnetic with ferromagnetic Ni, Fe, and Co alloyed L12 structure. The fully Cr-ordered phase to have a magnetic moment that 36% for magnetically frustrated random solid solution. Three samples were synthesized milling or casting/annealing. cast/annealed sample found low temperature 44% milled...
