Claim 10:
11. A method of preparing a high entropy alloy structure comprising the steps of:
A) preparing a melted alloy by arc melting raw materials comprising five or more elements;
B) drop casting the melted alloy into a cooled mold to form a bulk alloy;
C) applying an external force against the bulk alloy to reshape the bulk alloy; and
D) heat-treating the reshaped bulk alloy;
wherein the bulk alloy is reshaped and/or heat-treated for manipulating the distribution of the microstructure therein; and
wherein the high entropy alloy structure comprises cobalt, nickel, chromium, iron, and aluminum, in an atomic ratio of 30:30:20-0.5x:20-0.5x:x, wherein x is an integer from 14-20, and wherein the high entropy alloy structure comprises a eutectic high entropy alloy structure.
