Microstructure Analysis thiab Optimization Kho
Microstructure Observation Methods: Metallographic microscopes thiab electron microscopes (xws li Scanning Electron Microscope (SEM) lossis Transmission Electron Microscope (TEM)) yog siv los soj ntsuam cov microstructure ntawm steel phaj tom qab normalizing. Cov kev soj ntsuam tseem ceeb yog qhov loj thiab cov duab ntawm cov nplej thiab seb puas muaj cov microstructures txawv txav (xws li Widmanstätten qauv thiab lwm yam microstructures uas yuav txo tau cov toughness). Piv txwv li, los ntawm lub tshuab ntsuas metallographic, nws tuaj yeem pom ncaj qha seb cov nplej puas zoo ib yam. SEM tuaj yeem muab cov ncauj lus kom ntxaws ntxiv ntawm qhov chaw morphology thiab cov ntaub ntawv ciam teb.
Txheej txheem Optimization Raws li Microstructure: Yog hais tias cov nplej ntxhib los yog cov microstructures txawv txav, yuav tsum tau kho cov txheej txheem normalizing. Yog hais tias cov nplej yog ntxhib, nws yuav yog vim qhov kub thiab txias siab dhau los yog lub sijhawm tuav ntev dhau. Qhov kub thiab txias tuaj yeem txo qhov tsim nyog lossis lub sijhawm tuav tau luv. Yog tias cov qauv Widmanstätten tshwm, nws yuav yog vim qhov txias txias tsis tsim nyog. Koj tuaj yeem sim hloov txoj kev ua kom txias, xws li hloov los ntawm cua txias - cua txias mus rau ntuj huab cua - txias, ua kom zoo dua microstructure thiab txhim kho toughness.

Xav txog kev ua tau zoo ntawm kev tsim khoom thiab cov nqi tsim nyog
Kev txhim kho ntawm Kev Ua Haujlwm Zoo: Nyob rau hauv lub premise ntawm kev ua tau zoo ntawm cov hlau phaj, sim xaiv cov normalizing txheej txheem tsis muaj peev xwm txhim kho ntau lawm efficiency. Piv txwv li, ua kom cov cua sov kom tsim nyog (tsis ua rau overheating ntawm steel phaj los yog tsis-zoo li microstructure) thiab cov cua txias yuav txo tau lub normalizing lub sij hawm ntawm ib tug steel phaj, yog li txhim kho ntau lawm efficiency. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias ceev ceev cua sov lossis cua txias tuaj yeem ua rau muaj kev ntxhov siab sab hauv lossis lwm yam tsis xws luag hauv cov phaj steel, yog li kev hloov kho yuav tsum tau ceev faj.
Nqi - Tswj kev txiav txim siab: Tus nqi kuj yog ib qho tseem ceeb hauv kev txiav txim siab qhov zoo tshaj plaws normalizing txheej txheem. Xaiv cov khoom siv cua sov kom tsim nyog thiab cov khoom siv hluav taws xob tuaj yeem txo cov nqi siv hluav taws xob. Piv txwv li, kev siv cov cuab yeej siv hluav taws xob ua kom muaj hluav taws xob muaj zog tuaj yeem ua kom muaj zog ntau dua li cov khoom siv hluav taws xob ua kom sov. Nyob rau tib lub sijhawm, xav txog yam xws li cov khoom siv tu cov nqi thiab cov khoom siv poob thaum lub sijhawm ua haujlwm zoo, cov txheej txheem kev lag luam feem ntau tuaj yeem txiav txim siab los ntawm kev txiav txim siab.
