Qhov sib txawv tseem ceeb ntawm kev kho cua sov thiab tsis kub-kho cov alloys yog cov khoom siv hluav taws xob kho cua sov yog tsim los ntawm kev kho cua sov ua raws li kev sib ntxiv ntawm cov ntsiab lus alloying, qhov uas tsis yog-kub-kho tau alloys yog tsim los ntawm qhov sib ntxiv. ntawm alloying ntsiab ua raws li kev kho cua sov txheej txheem.
Kub-kho tau alloys yog cov khoom sib xyaw ntawm cov hlau thiab cov khoom tsis yog xim hlau uas muaj cov ntshiab txhuas uas tau ua kom sov mus txog ib qho chaw. Cov alloys uas tsis yog cua sov-kho tau yog aluminium alloys uas tau ua ke nrog cov ntsiab lus alloying ua ntej kev kho cua sov.
Cov khoom siv cua sov yog dab tsi?
Kub-kho tau alloys yog cov khoom sib xyaw ntawm cov hlau thiab cov khoom tsis yog xim hlau uas muaj cov ntshiab txhuas uas tau ua kom sov mus txog rau qee qhov taw tes, ua raws li qhov sib ntxiv ntawm cov hlau alloying homogenously. Qhov sib ntxiv ntawm cov khoom siv alloying ua rau cov txhuas ua khoom. Txawm li cas los xij, qhov sib tov no tseem nyob ntawm qhov kub siab uas yog tom qab ntawd quenched los ntawm kev txias sai. Qhov txias txias sai tuaj yeem ua rau cov atoms ntawm cov hlau alloy kom khov rau hauv qhov chaw.
Feem ntau, cov khoom siv hluav taws xob kho tau zoo thaum lub txhuas atoms thiab cov hlau alloy atoms zoo li sib xyaw ua ke thaum lub sij hawm kev laus ntawm chav tsev kub. Qee lub sij hawm, qhov no ua tiav los ntawm kev laus laus hauv lub cub tawg ntawm qhov kub thiab txias.
Raws li Aluminium Association Administers, cov ntaub ntawv kub-kho tau alloy yog tsim nrog cov ntsiab lus sib txawv. Qhov no ua rau lawv muab faib ua ntau pawg tshwj xeeb. Cov kev faib tawm no muaj npe siv 4 tus lej. Cov khoom siv alloying siv rau cov alloy yog qhia los ntawm thawj tus lej. Tus lej thib ob muab cov kev hloov kho ua rau cov khoom siv hauv paus alloy thaum tsim cov hlau no. Ob tus lej kawg qhia txog qhov tsawg kawg nkaus ntawm cov ntsiab lus txhuas hauv cov hlau. Cov pab pawg coob tshaj plaws tuaj li 2xxx, 6xxx, thiab 7xxx.
Rau qhov kub-kho tau 2xxx aluminium alloys, tooj liab yog siv los ua cov khoom siv alloying. Nyob rau hauv 6xxx tshav kub-kho aluminium alloys, cov khoom siv alloying siv yog silicon los yog magnesium, los yog ob qho tib si. Ntxiv mus, nyob rau hauv 7xxx tshav kub-kho aluminium alloy, peb siv zinc ua lub alloying caij.
Dab tsi yog cov khoom tsis muaj cua sov kho tau?
Tsis yog-kub-kho tau alloys yog aluminium alloys uas ua ke nrog cov ntsiab lus alloying ua ntej kev kho cua sov. Thaum pib, lub zog ntawm cov alloys yog ua tiav los ntawm kev sib ntxiv ntawm lwm cov ntsiab lus. Muaj ntau hom kev sib txawv ntawm cov hlau tsis muaj cua sov, suav nrog cov ntshiab aluminium alloys, manganese alloys, silicon alloys, thiab magnesium alloys. Kev nce ntxiv hauv lub zog ntawm hom alloy no tau txais los ntawm ntau hom kev ua haujlwm txias thiab cov txheej txheem tawv tawv.
Cov kev ua haujlwm txias tshaj plaws thiab cov txheej txheem tawv tawv muaj xws li dov, kos duab los ntawm kev tuag, ncab, lossis kev ua haujlwm zoo sib xws uas peb tuaj yeem tau txais qhov txo qis. Cov khoom kawg ntawm cov alloy yog txiav txim siab los ntawm tag nrho cov kev txo qis hauv cheeb tsam ntawm cov khoom siv. Ntxiv mus, "stabilizing" yog txheej txheem kub siab uas tuaj yeem ua kom ntseeg tau tias cov khoom siv kho tshuab kawg tsis hloov lub sijhawm.
Qhov txawv ntawm Cov Kub-kho tau thiab Tsis-kub-kho Alloys yog dab tsi?
Kub-kho tau alloys yog cov khoom sib xyaw ntawm cov hlau thiab cov khoom tsis yog xim hlau uas muaj cov ntshiab txhuas uas tau ua kom sov mus txog ib qho chaw. Non-heat-treatable alloys yog aluminium alloys uas tau ua ke nrog cov ntsiab lus alloying ua ntej kev kho cua sov. Qhov sib txawv tseem ceeb ntawm kev kho cua sov thiab tsis kub-kho tau alloys yog cov khoom siv hluav taws xob kho cua sov yog tsim los ntawm kev kho cua sov ua raws li kev sib ntxiv ntawm cov ntsiab lus alloying, whereas tsis-kub-kho alloys yog tsim los ntawm kev sib ntxiv ntawm cov ntsiab lus alloying ua raws li. Cov txheej txheem kho cua sov.
Cov hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv ntawm cov cua sov-kho thiab tsis-kub-kho cov alloys hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Kub-kho tau vs Tsis-kub-kho Alloys
Kub-kho tau alloys yog cov khoom sib xyaw ntawm cov hlau thiab cov khoom tsis yog xim hlau uas muaj cov ntshiab txhuas uas tau ua kom sov mus txog ib qho chaw. Non-heat-treatable alloys yog aluminium alloys uas tau ua ke nrog cov ntsiab lus alloying ua ntej kev kho cua sov. Qhov sib txawv tseem ceeb ntawm kev kho cua sov thiab tsis kub-kho tau alloys yog cov khoom siv hluav taws xob kho cua sov yog tsim los ntawm kev kho cua sov ua raws li kev sib ntxiv ntawm cov ntsiab lus alloying, whereas tsis-kub-kho alloys yog tsim los ntawm kev sib ntxiv ntawm cov ntsiab lus alloying ua raws li. Cov txheej txheem kho cua sov.
