Yog cua sov txias tsim nyog rau annealing? Kev tsim kho kom zoo ntawm kev kho cua sov
Lub Hom Phiaj Ntawm Annealing:

Annealing yog siv los hloov lub cev nqaij daim tawv thiab tshuaj lom neeg ntawm cov khoom siv sab hauv, txhim kho kev sib cav sib ceg, thiab kho teeb micructiviture}}}
Annealing yog siv rau ob qho tib si ferrous thiab tsis-ferrous allots thiab feem ntau yog siv los npaj cov khoom rau kev ua ntxiv lossis txhawm rau txhim kho cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov khoom siv ntawm cov ntaub ntawv.
Cov theem cua sov:

Cov khoom siv yog rhuab saum toj no nws recrystallization kub, nyob rau ntawm lub crystal qauv ua kua tab sis seem sawb .
Qhov no tso cai rau qhov tsis xws luag nyob rau hauv cov khoom siv rau kev kho tus kheej, ua rau muaj kev sib txawv ntxiv sab hauv {}}
Cua txias ua:

Cov txheej txheem txias yog qhov tseem ceeb hauv kev txiav txim siab cov khoom kawg ntawm cov khoom .
Qeeb thiab tswj cua txias (xws li cua txias txias) feem ntau siv los tau txais muag muag, ductile microstructure .
Sai sai txias kuj tseem siv tau hauv qee kis, tab sis yuav ua rau muaj kev hardness thiab txo ductility .
Hom cua txias hauv annealing:

Cua txias ua kom sov: Qhov no yog cov qauv ntau tshaj plaws, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob rau hauv qhov cub thiab tswj hwm.
Cua txias: Hauv qee kis, cov khoom tuaj yeem raug tshem tawm ntawm lub cub tawg thiab tso cai kom txias dua li cua txias .
Yuam kev txias txias: nyob rau hauv cov txheej txheem xws li cov cua txias ci tuaj yeem yuam kom txias dua cov khoom kom txias dua thaum ua kom zoo nkauj .
Qhov tseem ceeb ntawm kev tsim cua txias:

Kev tswj kom txias kom ntseeg tau tias cov khoom tau ua tiav cov qauv microstructure, xws li lub ntsej muag zoo nkauj lossis txo sab hauv kev ntxhov siab {}}
Nws kuj tseem tiv thaiv qhov tsim ntawm cov theem tsis xav tau lossis cov qauv uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob .
Kev txiav txim siab tshwj xeeb rau kev ci ntsa iab:

Ci annaling: nyob rau hauv kev sib tw ci ci, tus txheej txheem txias yog ua tib zoo tswj kom tiv thaiv oxidation lossis paug ntawm cov khoom saum npoo .
Xyuas li qub yog siv los tiv thaiv oxygen lossis lwm yam roj av los ntawm kev nkag mus rau cov khoom cub, kom pom tseeb tias cov khoom tseem ci thiab dawb.
Hom annealing thiab txoj kev ua kom txias:

Tag nrho annealing: feem ntau ua kom tiav kom ua tiav cov muag muag, ductile qauv .
Txheej Txheem Annaling: qeeb qeeb tus nqi yuav siv tau los daws qhov kev ntxhov siab tsis muaj teeb meem hloov kho microstructure .
Spheroidizing: cov cua sov ntev thiab qeeb cua txias feem ntau yuav tsum tau tsim ib qho spheroidal microstructure uas txhim kho tshuab luam ntawv txhim kho tshuab luam ntawv.
Kev txiav txim rau cov ntaub ntawv tshwj xeeb:

Cov txheej txheem txias tuaj yeem sib txawv ntawm cov khoom siv rau cov khoom siv uas xav tau kom ua tiav cov khoom siv uas xav tau qeeb, thaum muaj qee tus nqi txias nrawm dua.
Hauv cov ntsiab lus, thaum lub cub tawg yog ib qho kev ua kom muaj txiaj ntsig thiab lwm txoj kev ua kom txias, thiab lwm yam kev xav tau ntawm cov khoom cua txias
