The ingots of CuxZnMnNi (x = 1,2) medium-entropy (ME) brasses were fabricated using metallic mold-casting process without a vacuum chamber. The molten metal was obtained by high-frequency melting of the mixture of pure Cu, pure Ni, and pre-alloy i...

Deformation behavior of equiatomic HfNbTaTiZr high entropy alloy single crystals and polycrystals were investigated. The single crystalline specimens could be obtained from the coarse-grained polycrystals annealed just below the melting point. 1/2...
Applying empirical alloy parameters (including Mo equivalent), the predicted ground state diagram, and thermodynamic calculations, noble nonequiatomic Ti–Zr–Hf–Nb–Ta–Mo high-entropy alloys for metallic biomaterials (BioHEAs) were designed and newl...
