1. Cov pa roj carbon monoxide yog ib qho tseem ceeb uas cuam tshuam rau lub siab nyiam quenching. Cov ntsiab lus carbon nce, MS point txo, thiab quenching nyiam nce. Yog li ntawd, nyob rau hauv qhov kev txaus siab ntawm cov khoom siv xws li hardness thiab lub zog, cov ntsiab lus carbon tsawg yuav tsum raug xaiv kom ntau li ntau tau los xyuas kom meej tias nws tsis yooj yim rau quench.
2. Kev cuam tshuam ntawm cov ntsiab lus ntawm cov ntsiab lus quenching feem ntau yog tshwm sim hauv kev cuam tshuam ntawm quenchability, MS point, grain loj loj hlob nyiam thiab decarbonisation. Kev cuam tshuam ntawm cov ntsiab lus alloy ntawm quenchability cuam tshuam rau quenching nyiam. Feem ntau hais lus, quenchability nce, tab sis thaum lub quenchability nce, quenching nruab nrab nrog tsis muaj zog cua txias peev xwm yuav siv tau los tiv thaiv lub deformation thiab tawg ntawm complex qhov chaw los ntawm kev txo quenching deformation. Yog li ntawd, rau qhov chaw nrog cov duab nyuaj, txhawm rau kom tsis txhob quenching cov kab nrib pleb, nws yog ib qho kev xaiv zoo dua los xaiv cov hlau nrog zoo quenchability thiab siv quenching xov xwm nrog tsis muaj zog cua txias.
Cov ntsiab lus alloy muaj qhov cuam tshuam ntau dua ntawm MS point. Feem ntau hais lus, qhov qis dua MS steel, qhov ntau dua qhov kev xav quenching. Thaum MS taw tes siab, lub martensite tsim los ntawm theem kev hloov pauv tuaj yeem raug tempered tam sim ntawd, yog li tshem tawm ib feem ntawm cov theem hloov kev ntxhov siab thiab tsis txhob quenching. Yog li ntawd, thaum cov ntsiab lus carbon tau txiav txim siab, me me ntawm cov ntsiab lus hlau lossis hlau uas tsis tshua muaj kev cuam tshuam rau MS cov ntsiab lus yuav tsum raug xaiv.
3. Thaum xaiv cov hlau, overheat rhiab heev yuav tsum tau xav txog. Overheating thiab rhiab hlau yog ib qho yooj yim los tsim cov kab nrib pleb, yog li kev saib xyuas yuav tsum tau them rau thaum xaiv cov khoom.
