Cov cub tawg uas kub hnyiabtab tom hloov pauv txoj kev kho cua sov ntawm cov ntaub ntawv kev lag luam. Los ntawm kev tsim kom muaj ib puag ncig tswj hwm nruj, cov cub tawg no muaj peev xwm ua kom cov khoom siv kub raws li qhov tseeb, ua rau muaj cov khoom siv kho tshuab zoo dua.
Kev ua kom sov yog ib qho txheej txheem tseem ceeb rau ntau yam khoom siv hauv kev lag luam, suav nrog hlau thiab lwm yam hlau sib xyaw. Nws cuam tshuam nrog kev ua kom sov rau ib yam khoom siv rau qhov kub tshwj xeeb thiab tom qab ntawd txias nws raws li qhov xwm txheej tswj tau. Cov txheej txheem no hloov cov qauv me me ntawm cov khoom siv, ua rau muaj zog thiab ductility ntau dua. Cov cub tawg tempering ntxiv ib txheej ntxiv ntawm kev tswj hwm los ntawm kev tshem tawm cov khoom tsis huv thiab tswj cov pa roj nyob ib puag ncig cov khoom siv thaum lub sijhawm ua kom sov thiab txias.
Cov txiaj ntsig ntawmlub tshuab nqus tsev temperingmuaj ntau yam. Los ntawm kev tshem tawm huab cua thiab lwm yam tsis huv, cov chaw tsim khoom tuaj yeem tsim cov khoom huv dua, sib xws dua. Kev tswj qhov kub thiab txias kom raug kuj tso cai rau cov txheej txheem tempering kom raug dua, txhim kho cov khoom zoo thiab sib xws.
Ntxiv rau cov txiaj ntsig no, cov cub tawg uas siv lub tshuab nqus tsev kuj tseem siv hluav taws xob tsawg, ua rau cov chaw tsim khoom txuag tau cov nqi tsim khoom. Cov thev naus laus zis no kuj muaj cov yam ntxwv kev nyab xeeb zoo dua, suav nrog kev tswj hwm tsis siv neeg thiab cov txheej txheem kev nyab xeeb uas ua rau hauv.
Zuag qhia tag nrho, thev naus laus zis ntawm lub tshuab nqus tsev tempering yog ib qho kev txhim kho zoo siab hauv kev tshawb fawb txog cov ntaub ntawv. Nrog rau qhov kev thov nce ntxiv rau cov ntaub ntawv lag luam zoo, cov chaw tsim khoom tuaj yeem vam khom cov chaw tsim khoom no los tsim cov khoom uas meej thiab sib xws li sai tau. Los ntawm kev nqis peev rau hauv lub tshuab nqus tsev tempering, cov chaw tsim khoom tuaj yeem cia siab tias yuav txhim kho qhov zoo, kev siv hluav taws xob zoo thiab txuag cov nqi hauv cov txheej txheem tsim khoom.
