Metallic Materials​

  • ​Design of high-strength and thermally stable high-entropy alloys (HEAs) using novel fabrication and testing techniques.

Sample preparation of HEAs: (a) the bulk coarse-grained HEAs produced by arc melting and (c) the inverse pole figure map of the bulk HEAs; (b) the thin-film nanocrystalline (<100 nm grain size) HEAs produced by the magnetron co-sputtering system equipped with four targets arranged in a symmetry, and (d) their inverse pole figure map showing  texture.
