High entropy alloy (HEA) yog ib hom tshiab hlau alloy tsim nyob rau hauv xyoo tas los no.Nws muaj pes tsawg leeg yog tsim los ntawm tsib lossis ntau dua hlau.HEA yog ib qho ntawm cov txheej txheem ntawm cov hlau tseem ceeb (MPEA), uas yog cov hlau alloys uas muaj ob lossis ntau lub ntsiab lus tseem ceeb.Zoo li MPEA, HEA muaj npe nrov rau nws lub cev zoo tshaj plaws thiab cov khoom siv kho tshuab tshaj li cov khoom siv ib txwm muaj.
Cov qauv ntawm HEA feem ntau yog ib lub cev-centered cubic qauv los yog lub ntsej muag-centered cubic qauv, nrog lub zog siab, hardness, zoo heev hnav tsis kam, corrosion kuj, tsis kub tsis kam, kub oxidation kuj thiab tempering softening kuj.Nws tuaj yeem txhim kho qhov hardness, corrosion kuj, thermal stability thiab siab stability ntawm cov khoom.Yog li ntawd, nws yog dav siv nyob rau hauv cov ntaub ntawv thermoelectric, mos magnetic ntaub ntawv thiab hluav taws xob resistant ntaub ntawv
Lub siab entropy alloy ntawm FeCoNiAlSi system yog ib qho kev cog lus mos cov khoom sib nqus nrog siab saturation magnetization, resistivity thiab zoo heev plasticity;FeCrNiAl siab entropy alloy muaj cov khoom siv zoo thiab lub zog tawm los, uas muaj qhov zoo dua li cov ntaub ntawv binary zoo tib yam.Nws yog lub ntsiab lus kub ntawm kev tshawb fawb ua haujlwm hauv tsev thiab txawv teb chaws.Tam sim no txoj kev npaj ntawm high entropy alloy yog tsuas yog smelting txoj kev, uas coincides nrog peb lub tuam txhab txoj kev smelting.Peb tuaj yeem kho HEA nrog cov khoom sib txawv thiab cov kev qhia tshwj xeeb raws li cov neeg siv khoom xav tau
