Khoom Description
Cov ntsiab lus ntawm carbon nyob rau hauv cov tshuaj muaj pes tsawg leeg muaj feem xyuam rau lub toughness ntawm steel phaj.
Ntawm ib sab, kev nce qib hauv cov ntsiab lus carbon tuaj yeem txhim kho lub zog ntawm steel phaj. Txawm li cas los xij, raws li cov ntsiab lus ntawm cov pa roj carbon monoxide nce siab tshaj ib theem, nws muaj kev cuam tshuam tsis zoo rau cov tawv nqaij.
Thaum cov ntsiab lus carbon yog qhov siab, cov hlau yuav nyuaj thiab nkig. Qhov no txhais tau hais tias cov hlau phaj yog feem ntau yuav tawg nyob rau hauv kev cuam tshuam los yog kev ntxhov siab es tsis txhob deform nyob rau hauv ib tug ductile yam. Cov ntsiab lus carbon siab ua rau tsim cov ntxhib microstructure, uas txo cov peev txheej ntawm cov hlau kom nqus tau lub zog thaum raug rau sab nraud. Yog li ntawd, lub toughness ntawm steel phaj yog ho txo.
Ntawm qhov tod tes, cov ntsiab lus qis dua feem ntau ua rau cov hlau softer thiab ntau dua. Qhov no tso cai rau cov phaj hlau kom deform mus rau qee yam ua ntej tawg, qhia tias zoo dua toughness. Nrog tsawg carbon, lub microstructure ntawm cov hlau yog finer, ua kom nws muaj kev tiv thaiv zoo dua rau tawg propagation thiab txhim kho muaj peev xwm nqus los cuam tshuam lub zog.
Hauv cov ntsiab lus, qhov sib npaug tsim nyog ntawm cov ntsiab lus carbon yog qhov tseem ceeb rau kev ua tiav cov phaj steel nrog kev txaus siab toughness. Cov pa roj carbon ntau dhau txo cov tawv nqaij thiab ua rau cov hlau nkig, thaum cov pa roj carbon tsawg dhau tuaj yeem cuam tshuam lub zog.

Kho cov Alloy Ntxiv: Los ntawm kev ntxiv cov ntsiab lus tshwj xeeb xws li chromium, npib tsib xee, molybdenum, thiab lwm yam, hauv kev tswj cov nqi, cov khoom ntawm cov hlau tuaj yeem raug kho kom zoo. Cov alloying cov ntsiab lus no tuaj yeem txhim kho lub zog, toughness, corrosion kuj, thiab lwm yam ntxwv raws li qhov yuav tsum tau muaj rau cov qib sib txawv thiab kev siv cov nkoj tsim cov hlau.
Tswj cov theem impurity: Cov ntsiab lus ntawm impurities xws li sulfur thiab phosphorus tuaj yeem raug txo los ntawm kev siv cov txheej txheem kho kom zoo. Qhov no pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau los ntawm kev txo qis qhov tsis zoo ntawm cov impurities ntawm toughness, weldability, thiab lwm yam khoom.
Kho cov ntsiab lus piv txwv: Cov kev faib ua feem ntawm cov ntsiab lus xws li carbon, silicon, thiab manganese tuaj yeem hloov kho nyob rau hauv qee qhov kev txwv kom ua tiav cov khoom xav tau thiab lub cev. Piv txwv li, nce lossis txo cov ntsiab lus carbon tuaj yeem cuam tshuam rau lub zog thiab hardness ntawm cov hlau, thaum kho cov ntsiab lus ntawm manganese tuaj yeem cuam tshuam qhov toughness thiab ductility.
