High entropy alloy (HEA) bụ ụdị ọhụrụ metal alloy mepụtara na-adịbeghị anya.Ihe mejupụtara ya bụ ihe ọla ise ma ọ bụ karịa.HEA bụ akụkụ nke multi-primary metal alloys (MPEA), nke bụ metal alloys nwere isi ihe abụọ ma ọ bụ karịa.Dị ka MPEA, HEA bụ onye a ma ama maka njirimara anụ ahụ na arụ ọrụ ya dị elu karịa alloys ọdịnala.
