Qhov Tseem Ceeb Qhov txawv - Kev kho cua sov vs Annealing
Qhov sib txawv tseem ceeb ntawm kev kho cua sov thiab annealing yog tias annealing yog ib txoj kev kho cua sov. Cov txheej txheem kev kho cua sov muaj xws li cua sov thiab cua txias ua haujlwm ua ntu zus. Kev kho cua sov thiab cov txheej txheem annealing hloov cov qauv metallurgical thiab hloov lub cev, tshuaj, sib nqus thiab txhua yam khoom ntawm cov khoom.
kho cua sov suav nrog plaub txheej txheem tseem ceeb; normalizing, annealing, hardening thiab tempering.
Kev kho cua sov yog dab tsi?
Kev kho cua sov yog kev sib xyaw ua ke ntawm ob peb txheej txheem; cua sov ntawm tus nqi tshwj xeeb, soaking ntawm qhov kub thiab txias rau qee lub sijhawm, thiab thaum kawg txias ntawm tus nqi tshwj xeeb. Nws muaj cov txheej txheem saum npoo thiab ntau. Tag nrho cov txheej txheem no yuav pab hloov cov microstructure ntawm cov khoom. Txoj kev kho cua sov muab ntau qhov zoo rau tus txiv neej, hloov cov khoom siv ntawm cov hlau (lub cev, tshuab, sib nqus lossis hluav taws xob).
Cov txheej txheem feem ntau siv hauv cov txheej txheem kho cua sov yog annealing, tempering, hardening thiab normalizing. Ib txoj hauv kev los yog kev sib xyaw ua ke ntawm ntau txoj kev kho cua sov ua ke yog siv ib txhij kom tau txais cov khoom siv microstructure.

Yuav ua li cas?
Annealing yog txheej txheem siv hauv metallurgy; nws hloov lub cev thiab qee zaum tshuaj lom neeg ntawm cov khoom siv hlau. Annealing ua rau kom cov khoom tawg ntawm cov khoom siv kom nws ua haujlwm tau zoo dua. Nyob rau hauv annealing, cov khoom yog rhuab mus rau ib tug high kub, thiab ces nws yog txias ntawm ib tug heev tsawg tus nqi mus rau chav tsev kub. Cov khoom uas tshwm sim yog ductile thiab tawv, tab sis muaj tsawg hardness nqi.
- Ductility: lub peev xwm los deform cov khoom nyob rau hauv tensile stress.
- Toughness: lub peev xwm nqus tau lub zog thiab deform plastically tsis tawg. Hauv lwm lo lus, toughness yog lub zog ntawm ib chav tsev ntim uas cov khoom tuaj yeem nqus tsis tau tawg.
- Hardness: lub peev xwm ntawm cov khoom siv los tiv thaiv cov yas deformation. Cov ntaub ntawv nyuaj tsawg yog yooj yim deform thiab vise versa.
Annealing yog ua los ntawm cua sov cov khoom mus rau qhov kub thiab txias (qhov kub no txawv nyob ntawm qhov yuav tsum tau thiab hom hlau) nyob rau hauv lub cub tawg thiab ces nws yog tsau rau qhov kub ntawd. Tom ntej no, lub qhov cub raug kaw thaum hlau nyob hauv.
Dab tsi yog qhov sib txawv ntawm Kev Kho Kub Kub thiab Kev Ntsig?
Kev txhais ntawm Kev Kho Mob Kub thiab Kev Ntsig
Kev kho cua sov: Kev kho cua sov yog txheej txheem uas cov hlau tau rhuab mus rau ib qho kub thiab txias hauv ib qho tshwj xeeb los hloov nws cov qauv sab hauv kom tau txais qhov xav tau ntawm lub cev thiab cov khoom siv kho tshuab
Annealing: Annealing yog tus txheej txheem ntawm softening ib yam khoom (xws li iav), hlau (xws li cam khwb cia hlau), los yog ib tug alloy (xws li steel) kom nws tsis nkig los ntawm cua sov rau ib tug tshwj xeeb kub, tswj nws ntawm qhov kub thiab txias rau ib lub sijhawm tshwj xeeb, thiab txias nws maj mam mus rau qhov kub thiab txias ntawm tus nqi tshwj xeeb.
yam ntxwv ntawm kev kho cua sov thiab Annealing
Methods
Kev Kho Kub Kub: Feem ntau siv cov kev kho cua sov yog; annealing, normalizing, hardening thiab tempering.
Annealing: Feem ntau siv txoj kev annealing yog; Kev ntxhov siab, mos annealing, recrystallization annealing, standardized annealing, tov annealing, stabilization annealing thiab sib nqus annealing (permeable annealing).
txheej txheem
Annealing: Nws muaj peb kauj ruam tseem ceeb hauv cov txheej txheem.
- Cua cov khoom kom kub siab tshaj qhov ntsuas kub tseem ceeb.
- Tuav cov khoom ntawm qhov kub ntawd rau ib lub sijhawm.
- Cias ntawm tus nqi qeeb hauv qhov cub.
Kev ua kom txias yog ua tiav thaum tau txais cov khoom xav tau. Cov txheej txheem cua txias yuav tsum ua tiav ntawm qee qhov cua txias thaum tiv thaiv cov khoom tau txais.
Kev kho cua sov: Tag nrho lwm txoj kev kho cua sov muaj tib cov kauj ruam raws li saum toj no. Tab sis cov cua sov thiab cua txias thiab cov dej sov hloov pauv raws li qhov yuav tsum tau ua.
Hloov pauv hauv cov khoom
Annealing: Annealing hloov cov khoom nram qab no ntawm cov khoom.
- Txoj kev ntxhov siab.
- Txhim kho cov qauv ntawm cov khoom
- Txhim kho cov khoom sib nqus
- Txo cov tawv tawv
- Txhim kho cov khoom siv vuam
- Txhim kho qhov kev tiv thaiv corrosion
- Zoo qhov ntev thiab qhov tseeb
- txheej txheem huv, qhov chaw tseem ci
Kev kho cua sov: Hauv kev kho cua sov, cov txheej txheem sib txawv hloov cov khoom sib txawv. Qee qhov piv txwv muaj nyob hauv qab no.
- Ntau hardening, deg hardening - nce lub zog, hardness, thiab hnav tsis kam
- Tempering, recrystallization annealing - nce ductility thiab softness
- Tempering, recrystallization annealing - nce toughness.
- Recrystallization annealing, tag nrho annealing, normalizing - kom tau zoo grain loj
- Kev ntxhov siab rau kev ntxhov siab - tshem tawm cov kev ntxhov siab sab hauv
- tag nrho annealing thiab normalizing - txhim kho lub machinability
- Ua kom tawv thiab tempering - txhim kho cov khoom ntawm cov cuab yeej steel
- Recrystallization, tempering, hnub nyoog hardening - txhim kho cov khoom hluav taws xob.
- Hardening, theem hloov pauv - txhawm rau txhim kho cov khoom sib nqus.
