Dab tsi yog annealing? Qhia los txhim kho cov hlau hluavtaws los ntawm kev kho cua sov

Annealing yog lub tshav kub kho kom hloov pauv lub cev thiab cov tshuab cua sov kom muaj qhov kub thiab txias}} ib puag ncig . Tus txheej txheem annealing tau muab faib ua peb ntu

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog annealing? Qhia los txhim kho cov hlau hluavtaws los ntawm kev kho cua sov
Cua Sov Ntaus (Rauv):

Lub cub hluav taws xob yog qhov tseem ceeb ntawm cov cuab yeej siv uas yuav tsum muaj rau annealing {{000} Nws yuav tsum tau ncav cuag thiab 900 qhov cub tau tshaj 1000 degree.
Cov cua sov yuav tsum muaj cov cua sov kom ntseeg tau tias cov hlau mus txog qhov uas yuav tsum tau kub nyob rau hauv cov qauv .
Cov hom hluav taws xob siv tau suav nrog cov thawv refaces, huab cua cov cua sov, txhua qhov uas yuav tsum muaj .
Tswj kub:

Kev ntsuas qhov kub yog qhov tseem ceeb thaum lub annealing txheej txheem {}} Cov hlau yuav tsum tau ua kua dej, tab sis tseem tseem nyob twj ywm .
Qhov kub no sib txawv nyob ntawm seb cov hlau ua annealed . Piv txwv, steel feem ntau yuav tsum muaj qhov kub thiab txias dua li txhuas lossis tooj liab.
Tswj qhov ntsuas kub kom raug kom meej meej uas tsis xws luag nyob rau hauv cov khoom tuaj yeem kho tau lawv tus kheej, txhim kho cov khoom siv .
Annealing Theem:

Rov qab: nyob rau theem no, cov hlau yog rhuab rau ib qho kub uas tso cov qauv sib luag yam tsis muaj kev hloov pauv cov hlau rau lwm tus tom ntej.
Recrystallization: cua sov cov hlau saum toj no nws qhov recrystallization kub tso cai rau cov khoom siv tshiab {1} {{2 {2}
Grain kev loj hlob: yog tias cov hlau muaj nyob ntawm Anealing Kub rau ntev heev, cuam tshuam cov khoom siv cov khoom siv tshuab ntau dhau lawm {}}
Cov txheej txheem cua txias:

Tom qab cov hlau tau muaj nyob ntawm Anealing Kub, nws yuav tsum maj mam txias rau chav kub {}}} negate cov txiaj ntsig ntawm annealing.
Ua tib zoo tswj ntawm tus nqi txias kom ntseeg tau tias kev tsim kho crystalline yog tsim, uas txhim kho cov hlau ua haujlwm thiab txo qis brittleness .
Cov ntaub ntawv tsim nyog rau annaling:

Cov hlau hlau thiab cov hlau hlau feem ntau yog annealed, tab sis lwm cov hlau xws li txhuas, tooj dag, thiab tooj kuj tseem muaj annealed .
Txhua tus hlau muaj qhov ntsuas kub thiab txias thiab txias thiab txias dua thiab txias dua uas yuav tsum tau ua raws li qhov ua tau zoo tshaj plaws}
Cov cuab yeej hloov pauv:

Cov thawv ntim hluav taws: Cov no yog ntau yam thiab tuaj yeem coj ntau yam khoom siv thiab ntau {} Lawv tsim nyog rau kev ua .
Cov huab cua sov hluav taws xob: Cov chaw ua hluav taws xob no tswj cov hlau kom tiv thaiv oxidation lossis lwm yam zoo tagnrho rau cov khoom siv uas rhiab rau cov khoom siv atmospheric {}}
Lub tshuab nqus tsev kom zoo: Siv rau cov ntaub ntawv siab muaj siab lossis cov khoom siv uas xav tau cov pa roj oxygen
Cov ntawv thov thiab cov txiaj ntsig:

Annealing yog siv los txhim kho lub tshuab luam ntawv, ductility, thiab tawv ntawm cov hlau .
Annealing yog feem ntau siv nyob rau hauv kev lag luam xws li Automotive, Aerospace, thiab kev tsim khoom, qhov twg hlau seem yuav tsum tau tiv thaiv kev ntxhov siab thiab deformation .
Tus txheej txheem kuj tseem txhim kho cov hlau xws li tooj liab, uas ua si lub luag haujlwm tseem ceeb hauv cov ntaub ntawv hluav taws xob thiab hluav taws xob {}}
Los ntawm kev nkag siab cov ntsiab lus no, cov cuab yeej siv lossis cov neeg yuav khoom tuaj yeem xaiv tau cov kev txiav txim siab thiab annealing txheej txheem rau cov ntaub ntawv tshwj xeeb thiab cov ntawv thov.
