by arc-melting. It is found that, this Co-free as-cast HEA is mainly composed of fine FCC and
BCC phases that have close correlation with solid-state phase transformation during cooling
after solidification. It shows high mechanical properties combining ultimate tensile strength
of∼ 1130 MPa and plasticity of∼ 8%. Moreover, it also has good corrosion resistance
comparable to stainless steels. This work provides a novel route for designing high …
