Kev kho cua sov: Cov txheej txheem kev kho cua sov sib txawv muaj qhov cuam tshuam loj heev rau lub zog ntawm cov ntaub ntawv. Piv txwv li, quenching yog ib qho txheej txheem kev kho cua sov. Nws heats cov khoom saum toj no qhov tseem ceeb kub, tuav nws rau ib lub sij hawm ntawm lub sij hawm, thiab ces sai txias nws. quenching tuaj yeem ua rau cov hlau ua cov qauv martensite. Martensite muaj cov yam ntxwv ntawm siab hardness thiab siab zog. Tempering yog txheej txheem kev kho cua sov ua tom qab quenching. Los ntawm tempering, qhov sib npaug ntawm lub zog thiab toughness ntawm cov khoom tuaj yeem hloov kho. Rau qee cov pa roj carbon monoxide siab, tom qab quenching thiab tsim nyog tempering, lub toughness ntawm cov khoom tuaj yeem txhim kho thaum tuav lub zog siab, ua rau nws tsim nyog rau kev siv engineering.
Ua haujlwm txias thiab ua haujlwm kub: Cov txheej txheem ua haujlwm txias xws li txias dov thiab kos duab txias tuaj yeem ua rau cov khoom ua haujlwm nyuaj. Thaum lub sij hawm ua hauj lwm txias, cov nplej ntawm cov khoom yuav elongated raws li kev ua hauj lwm kev taw qhia, thiab dislocation ceev yuav ho nce, yog li ua kom lub zog ntawm cov khoom. Txawm li cas los xij, kev ua haujlwm txias ntau dhau tuaj yeem ua rau muaj qhov tsis zoo ntawm qhov toughness thiab ductility ntawm cov khoom. Cov txheej txheem ua haujlwm kub xws li kub dov tuaj yeem cuam tshuam lub zog ntawm cov khoom los ntawm kev hloov qhov loj thiab cov duab ntawm cov nplej. Cov txheej txheem ua haujlwm kub tsim nyog tuaj yeem kho cov nplej, ua kom lub zog thiab tawv ntawm cov khoom.

Environmental Factors
Kub: Kub muaj feem cuam tshuam rau lub zog ntawm cov ntaub ntawv. Nyob rau hauv ib puag ncig uas tsis kub, qee cov ntaub ntawv yuav nthuav tawm embrittlement. Txawm hais tias lub zog yuav tsis hloov ntau, lub toughness yog txo qis. Piv txwv li, nyob rau hauv cov hlau nrog lub cev-centered cubic qauv (xws li hlau), kev tiv thaiv rau lub zog ntawm dislocations nce nyob rau hauv ib tug tsawg-kub ib puag ncig, thiab cov khoom yog nquag mus nkig tawg. Nyob rau hauv ib qho chaw kub kub, lub thermal zog ntawm atoms nyob rau hauv cov khoom intensifies, thiab lub binding quab yuam ntawm atoms tsis muaj zog, ua rau ib tug txo nyob rau hauv lub zog ntawm cov khoom. Rau high-temperature alloys, lawv lub hom phiaj tsim yog kom muaj lub zog muaj zog thiab zoo antioxidant zog nyob rau hauv ib puag ncig kub kom tau raws li qhov xav tau ntawm aerospace thiab lwm yam kev lag luam.
Corrosion Ib puag ncig: Thaum cov khoom siv nyob rau hauv ib puag ncig corrosion, tshuaj lom neeg cov tshuaj tiv thaiv yuav tshwm sim ntawm nws qhov chaw, uas ua rau poob ntawm cov khoom siv. Piv txwv li, cov ntaub ntawv hlau yuav corrode nyob rau hauv acidic los yog alkaline daws. Thaum lub sij hawm txheej txheem corrosion, corrosion pits yuav tsim nyob rau saum npoo ntawm cov khoom. Cov pits corrosion no yuav dhau los ua cov ntsiab lus kev ntxhov siab. Thaum cov khoom raug rau sab nraud quab yuam, cov kab nrib pleb zoo li yuav raug tsim los ntawm cov ntsiab lus kev ntxhov siab, yog li txo lub zog ntawm cov khoom. Nyob rau hauv ib puag ncig marine, vim corrosiveness ntawm seawater, ntau cov qauv hlau (xws li lub hulls ntawm ships, offshore platforms, thiab lwm yam) yuav tsum tau txais tshwj xeeb los tiv thaiv corrosion los tiv thaiv lub zog poob.
