In reserch of HEA, much of them is about equivalent alloys, while there is little research on non-equivalent. Therefore, non-equivalent alloys have possibility which they overcome equivalent alloys. So we apply Curtin model with some modification to Hf-Nb-Ta-Ti-Zr alloys, and aim for achieving strength that surpasses that of equivalent alloys.
