Cov khoom lag luam siab yog ib hom khoom tshiab nrog cov khoom lag luam zoo nkauj heev, uas tau txhim kho kom muaj kev ua haujlwm ntev ntxiv, uas tau txhim kho kev ua haujlwm ntev thiab ruaj khov ntawm Alloy.
Cov txheej txheem ntau lawm ntawm lub siab-entropy alloy kev lag luam
High-entropy alloys (Heas) yog ib qho khoom tshiab ntawm ib qho kev mob siab xws li muaj kev ua haujlwm siab zoo xws li muaj kev ua haujlwm siab, thiab muaj zog, thiab muaj zog. Cov kev tshawb fawb thiab cov ntawv thov ntawm HEACH ntau ntau ntawm cov teb, nrog rau kev lag luam, thiab cov tshuaj muaj kev lag luam hauv lub xyoo tom ntej.
Cov yam ntxwv ntawm lub siab-entropy alloy kev lag luam
Lub SMELING txheej txheem ntawm HEA sawv cev rau cov kev ua thev naus laus zis tshiab los tsim cov kev ua yeeb yam tshiab ntawm cov txheej txheem, yog li txhim kho kev ua tau zoo thiab ruaj khov ntawm alloy.
Muaj ob txoj hauv kev rau kev npaj ua kom:
{{0 {}} tshuab lwm yam (ma):
Koom nrog hmoov ntau ntawm ntau cov ntsiab lus thiab siv cov zog loj pob milling rau ntxias cov tshuaj lom neeg ntawm cov ntsiab lus, ua kom tawv tawv.
{{02. fusion alloying (FA):
Cuam tshuam nrog hmoov ntau ntawm ntau yam thiab yaj lawv thaum kub siab los tsim Heas .
Cov txheej txheem smeading yog cov tshiab thiab muaj txiaj ntsig zoo ntawm cov txheej txheem thiab kev txhim kho cov ntawv thov tseem ceeb rau tib neeg kev kawm {}}
Cov yam ntxwv tseem ceeb ntawm cov khoom siab siab entropy alloys
Multi-Quit Composition:
Heas yog tsim ntawm tsawg kawg tsib lossis ntau dua cov ntsiab . sib piv rau cov khoom siv dav dav, qhov kev ua tau zoo tshaj plaws nyob rau hauv cov chaw tsim khoom thiab kev ua haujlwm ntau dua}
Complex Crystal Cov Qauv:
Txawm li cas los xij, suav nrog kev ua kom muaj zog, thiab cov tshuaj zoo dua, thiab cov tshuaj zoo dua, thiab cov tshuaj zoo dua li.
High-entropy nyhuv:
Kev sib xyaw ua ke siab yog qhov tseeb ntawm lub tshuab hluav taws xob thiab kev ruaj khov ntawm cov khoom siv tshuaj lom neeg thiab cov khoom siv hluav taws xob zoo sib xws thiab cov khoom nruab nrab.
Kev Tsim Kho Kev Tsim Kho Hauv Lub High-Entropy Alloy Kev Lag Luam
Alloy Tsim:
Cov kev ua yeeb yam ntawm Heas yog ho cuam tshuam los ntawm theem pib muaj pes tsawg leeg thiab ua ntu zus ntxiv .
Cov qauv tsim qauv qauv tsim qauv, xws li cov ntaub ntawv siv computer tsim (camd), tso cai rau cov khoom siv hluav taws xob thiab kev ua kom zoo ntawm lub pob zeb.
Crystal qauv tswj:
Txawm li cas los xij ua rau muaj cov qauv siv lead ua nrog cov kev sib cuam tshuam nrog kev sib cuam tshuam nrog kev sib cuam tshuam nrog {}}
Kev Hloov Kho Cov Lus Cog Tseg lossis kho cov kev ua haujlwm ua kom muaj kev tswj hwm thiab ua kom zoo ntawm cov qauv siv lead ua {}}
Alloy Npaj Tswv Qhia:
Kev tso cai, kev kho cua sov, thiab cov txheej txheem cua txias tawm tsam kom tsim cov pob tesy .
Kev npaj npaj thev naus laus zis xws li kev siv tshuab xws li, thiab ntshav arc melting tam sim no yog tam sim no siv rau cov synthesis .
Multifunctional Cov Khoom:
HEAs muaj cov khoom tshwj xeeb, suav nrog cov tshuab hluav taws xob siab dua, kev siv hluav taws xob, hluav taws xob, thiab hlau nplaum.
Raws li cov khoom siv ntau yam ,,, tus neeg muaj kev cog lus rau cov ntaub ntawv, tsav tsheb tshiab hla kev lag luam .
