Qhov sib txawv tseem ceeb ntawm cov tshuaj sib xyaw sib xyaw thiab cov khoom sib xyaw ua ke yog cov sib xyaw sib xyaw ua ke muaj cov qauv sib xws, qhov sib txawv ntawm cov hlau alloys muaj cov qauv tsis sib xws.
Intermetallic compounds yog cov khoom uas muaj cov theem uas muaj xws li ob lossis ntau dua hlau los yog ib nrab-hlau uas tau teem rau hauv cov qauv txiav txim. Cov khoom siv tshuaj lom neeg yog ib hom khoom siv hlau uas tsim los txhim kho lub zog ntawm cov hlau ntshiab.
Yuav ua li cas yog cov tshuaj intermetallic?
Intermetallic compounds yog cov khoom uas muaj cov theem khoom thiab suav nrog ob lossis ntau dua metallic lossis semi-metallic ntsiab teeb tsa hauv cov qauv txiav txim. Peb tuaj yeem hu cov ntaub ntawv no ua intermetallic lossis intermetallic alloys. Feem ntau, cov tebchaw no muaj cov ntsiab lus zoo thiab ruaj khov stoichiometry. Feem ntau, intermetallic tebchaw yog ib qho nyuaj thiab nkig, muaj qhov kub-kub txhua yam khoom. Peb tuaj yeem faib cov ntsiab lus no yog stoichiometric thiab non-stoichiometric intermetallic compounds.
Thaum xav txog cov khoom thiab kev siv ntawm cov tshuaj no, lawv feem ntau muaj cov ntsiab lus melting siab thiab nkig ntawm chav tsev kub. Muaj peev xwm ua tau cleavage los yog intergranular fracture hom ntawm intermetallic tebchaw vim hais tias ntawm ib tug txwv ywj siab slip systems uas yuav tsum tau rau cov yas deformation. Txawm li cas los xij, muaj peev xwm muaj cov kab tawg tawg hom ntawm cov sib txuas intermetallic ib yam nkaus. Qhov ductility no tuaj yeem txhim kho hauv cov tebchaw no los ntawm kev sib xyaw lwm cov ntaub ntawv xws li boron, uas tuaj yeem txhim kho cov qoob loo ciam teb cohesion.
Qee cov piv txwv ntawm cov sib txuas sib txuas muaj xws li cov khoom sib nqus xws li alnico, sendust, thiab Permendur, superconductors xws li A 15 theem thiab niobium-tin, zoo li nco alloys, thiab lwm yam. Cov sib txuas sib txuas uas peb tuaj yeem nrhiav tau los ntawm keeb kwm suav nrog Roman daj tooj dag, Suav siab tin bronze thiab hom hlau, SbSn.
Dab tsi yog Solid Solution Alloys?
Cov kua dej khov yog ib hom khoom siv hlau uas tsim los txhim kho lub zog ntawm cov hlau ntshiab. Cov txheej txheem ntawm kev tsim cov khoom siv tshuaj alloy yog hu ua cov tshuaj tiv thaiv kom muaj zog. Cov txheej txheem no yog ua los ntawm kev sib ntxiv ntawm cov atoms ntawm ib lub caij mus rau cov qauv crystalline ntawm lwm lub caij, qhov qub lub caij yog lub npe hu ua alloying caij thiab tom kawg yog lub npe hu ua lub hauv paus hlau. Qhov kev sib ntxiv no tsim ib qho kev daws teeb meem.
Daim duab 01: Kev Hloov Kho Khoom Siv
Feem ntau, qhov sib ntxiv ntawm cov khoom siv hlau ua rau lub zos tsis sib xws hauv cov hlau ntshiab. Qhov no ua rau cov yas deformation nyuaj los ntawm kev txav mus los ntawm kev ntxhov siab. Ntawm qhov tod tes, alloying dhau qhov kev txwv tsis pub solubility tuaj yeem ua rau kev tsim ntawm theem thib ob uas ua rau muaj zog los ntawm lwm cov txheej txheem, xws li. tsim ntawm intermetallic compounds.
Daim duab 2: Kev daws teeb meem Interstitial
Muaj ntau hom kev daws teeb meem sib txawv, xws li cov khoom siv hloov pauv thiab cov kev daws teeb meem interstitial. Ob hom no txawv ntawm ib leeg raws li qhov loj ntawm cov khoom alloying. Yog hais tias cov khoom alloying atom loj dua qhov hnyav atom ntawm cov tshuaj, nws tuaj yeem hloov cov kuab tshuaj atoms hauv cov siv lead ua lattice thiab ua rau cov khoom siv hloov pauv. Yog hais tias lub atoms ntawm lub alloying caij yog me dua lub solute atoms, lawv zoo li haum rau hauv interstitial qhov chaw ntawm cov kuab atoms thiab tsim interstitial solid solutions.
Qhov txawv ntawm Intermetallic Compounds thiab Solid Solution Alloys
Intermetallic compounds thiab solid solutions alloys are alloys substances have mixtures of metals and/lossis nonmetals. Qhov sib txawv tseem ceeb ntawm intermetallic tebchaw thiab cov khoom siv tshuaj alloys yog tias cov tshuaj sib xyaw intermetallic muaj cov qauv sib xws, thaum cov khoom siv tshuaj alloys muaj cov qauv tsis sib xws.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm intermetallic tebchaw thiab cov khoom siv tshuaj alloys.
Summary – Intermetallic Compounds vs Solid Solution Alloys
Intermetallic compounds thiab solid solutions alloys are alloys substances have mixtures of metals and/lossis nonmetals. Qhov sib txawv tseem ceeb ntawm intermetallic tebchaw thiab cov khoom siv tshuaj alloys yog tias cov tshuaj sib xyaw intermetallic muaj cov qauv sib xws, thaum cov khoom siv tshuaj alloys muaj cov qauv tsis sib xws.
