I-High entropy alloy (HEA) uhlobo olusha lwe-alloy yensimbi olwakhiwe eminyakeni yamuva. Ukwakheka kwayo kwakhiwe izakhi zensimbi ezinhlanu noma ngaphezulu. I-HEA iyisethi engaphansi yama-multi-primary metal alloys (MPEA), okuyingxubevange yensimbi equkethe izakhi ezimbili noma ngaphezulu eziyinhloko. Njenge-MPEA, i-HEA idume ngezakhiwo zayo eziphakeme zomzimba nezomshini ngaphezu kwama-alloys endabuko.
Isakhiwo se-HEA ngokuvamile siyisakhiwo se-cubic esigxile emzimbeni owodwa noma isakhiwo se-cubic esigxile ebusweni, esinamandla amakhulu, ukuqina, ukumelana nokugqokwa okuhle kakhulu, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphansi, ukumelana nokushisa okuphezulu kwe-oxidation kanye nokumelana nokuthambisa ukuthambisa. Ingakwazi ukuthuthukisa ngokuphawulekayo ubulukhuni, ukumelana nokugqwala, ukuzinza kokushisa kanye nokuzinza kwengcindezi yento. Ngakho-ke, isetshenziswa kabanzi ezintweni ze-thermoelectric, izinto ezithambile zikazibuthe nezinto ezimelana nemisebe
I-entropy alloy ephezulu yesistimu ye-FeCoNiAlSi iyimpahla ethembisayo enozibuthe ene-high saturation magnetization, resistivity kanye nepulasitiki enhle kakhulu; I-FeCrNiAl high entropy alloy inezici ezinhle zemishini namandla esivuno, enezinzuzo ezinhle ngaphezu kwezinto ezijwayelekile kanambambili. Kuyisihloko esishisayo somsebenzi wocwaningo ekhaya naphesheya. Manje indlela yokulungiselela ye-high entropy alloy ngokuyinhloko iyindlela yokuncibilikisa, ehambisana nendlela yenkampani yethu yokuncibilikisa. Singakwazi ukwenza ngokwezifiso i-HEA ngezingxenye ezahlukene kanye nokucaciswa ngokuvumelana nezidingo zamakhasimende
