Qhov sib txawv tseem ceeb ntawm alloy thiab intermetallic compound yog tias cov alloys muaj cov khoom siv hlau thiab cov khoom tsis yog xim hlau, hos cov sib txuas intermetallic muaj cov khoom siv hlau lossis cov khoom semi-metallic.
Ib qho hlau yog cov khoom siv hlau uas muaj tsawg kawg ib lub hlau nrog rau lwm cov khoom. Intermetallic compounds yog cov ntaub ntawv uas muaj cov theem uas muaj ob los yog ntau dua metallic los yog semi-metallic ntsiab teeb meem nyob rau hauv ib tug txiav txim qauv.
Yuav ua li cas yog Alloy?
Alloys yog cov khoom siv hlau uas muaj tsawg kawg yog ib qho hlau nrog rau lwm cov khoom. Cov tshuaj no muaj cov khoom zoo dua qub thaum piv rau cov khoom ntawm txhua lub caij lawv tau ua los ntawm. Peb tuaj yeem tau txais cov khoom ntawm cov alloys los ntawm kev sib xyaw cov ntsiab lus hauv ntau feem pua. Yog li ntawd, lawv muab cov khoom xav tau los ntawm kev sib xyaw cov hlau sib txawv thiab cov khoom sib txawv. Yuav luag tag nrho cov alloys muaj luster vim muaj cov khoom siv hlau. Alloys kuj tuaj yeem ua hluav taws xob vim muaj cov khoom siv hlau.

Kev faib tawm ntawm Alloys
Peb tuaj yeem faib cov alloys hauv ntau txoj kev. Piv txwv li, lawv tuaj yeem ua homogenous lossis heterogeneous. Homogenous alloys muaj cov khoom faib thoob plaws hauv cov khoom sib xws. Heterogeneous alloys, ntawm qhov tod tes, muaj cov khoom faib tawm hauv qhov tsis sib xws.
Tsis tas li ntawd, muaj cov khoom hloov pauv thiab sib cuam tshuam. Cov hlau hloov pauv yog cov hlau alloys tsim los ntawm kev hloov ib lub atom hlau rau lwm cov hlau atom ntawm qhov loj me. Interstitial alloys yog cov hlau alloys tsim los ntawm kev ntxig me me atoms rau hauv qhov ntawm cov hlau lattice.
Intermetallic Compound yog dab tsi?
Intermetallic tebchaw yog cov khoom uas muaj cov theem uas muaj ob los yog ntau tshaj hlau los yog semi-metallic cov txheej txheem nyob rau hauv ib tug txiav txim qauv. Lawv kuj muaj npe hu ua intermetallic lossis intermetallic alloys. Feem ntau cov tebchaw no muaj cov ntsiab lus zoo thiab ruaj khov stoichiometry. Feem ntau, intermetallic tebchaw yog nyuaj thiab nkig, muaj high-temperature mechanical zog. Peb tuaj yeem faib cov ntsiab lus no ua stoichiometric thiab non-stoichiometric intermetallic compounds.

Khoom ntawm 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 yam piv txwv ntawm cov sib txuas sib nqus 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 khoom sib nqus intermetallic peb tuaj yeem nrhiav tau los ntawm keeb kwm muaj xws li Roman. daj tooj dag, Suav siab tin bronze thiab hom hlau, SbSn.
Qhov txawv ntawm Alloy thiab Intermetallic Compound yog dab tsi?
Alloys thiab intermetallic compounds yog cov khoom tseem ceeb hauv kev lag luam. Qhov sib txawv tseem ceeb ntawm alloy thiab intermetallic compound yog tias alloys muaj cov khoom siv hlau thiab cov khoom tsis yog xim hlau, hos cov sib txuas intermetallic muaj cov khoom siv hlau lossis cov khoom siv hlau. Bronze, tooj dag, steel, wrought hlau, cam khwb cia hlau, thiab stainless hlau yog cov piv txwv ntawm alloys whereas sib nqus cov ntaub ntawv xws li alnico, sendust, thiab Permendur, superconductors xws li A 15 theem thiab niobium-tin, zoo li nco alloys, thiab lwm yam yog intermetallic. sib xyaws.
Cov hauv qab no infographic teev qhov sib txawv ntawm alloy thiab intermetallic compound nyob rau hauv daim ntawv tabular.
Summary – Alloy vs Intermetallic Compound
Alloys thiab intermetallic compounds yog cov khoom tseem ceeb hauv kev lag luam. Qhov sib txawv tseem ceeb ntawm alloy thiab intermetallic compound yog tias alloys muaj cov khoom siv hlau thiab cov khoom tsis yog xim hlau, hos cov sib txuas intermetallic muaj cov khoom siv hlau lossis cov khoom siv hlau.
