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.
Ihe owuwu nke HEA n'ozuzu bụ otu akụkụ cubic nke dabere na ahụ ma ọ bụ usoro cubic nwere ihu, nwere ike dị elu, isi ike, nguzogide iyi kacha mma, nguzogide corrosion, nguzogide dị ala, nguzogide ikuku oxidation dị elu na nguzogide dị nro. Ọ nwere ike imeziwanye ike ike, nguzogide corrosion, nkwụsi ike nke okpomọkụ na nkwụsi ike nke ihe. Ya mere, a na-ejikarị ya eme ihe na ihe ọkụ ọkụ, ihe magnetik dị nro na ihe ndị na-eguzogide radieshon
Elu entropy alloy nke FeCoNiAlSi sistemụ bụ ihe ndọta dị nro na-ekwe nkwa nke nwere nnukwu saturation magnetik, resistivity na ezigbo plasticity; FeCrNiAl elu entropy alloy nwere ezigbo ihe eji arụ ọrụ ma na-enye ike, nke nwere nnukwu uru karịa ihe ọnụọgụ abụọ nkịtị. Ọ bụ isiokwu na-ekpo ọkụ nke ọrụ nyocha n'ụlọ na ná mba ọzọ. Ugbu a, usoro nkwadebe nke elu entropy alloy bụ tumadi usoro agbaze, nke dabara na usoro ụlọ ọrụ anyị. Anyị nwere ike hazie HEA na akụkụ dị iche iche na nkọwapụta dịka ihe ndị ahịa chọrọ
