Kev cai ntawm Microstructure

 

Kev siv cua sov - kev kho mob: Tsim nyog cov cua sov - cov txheej txheem kev kho mob tuaj yeem ua kom zoo dua qhov microstructure ntawm CCS A550 steel phaj thiab ntxiv dag zog rau lub zog. Piv txwv li, normalizing tuaj yeem ua rau cov qauv ntawm cov hlau zoo sib xws. Thaum lub sij hawm normalizing txheej txheem, cov hlau phaj yog rhuab mus rau ib tug tsim nyog kub thiab ces txias nyob rau hauv huab cua. Cov txheej txheem no tuaj yeem kho cov nplej thiab txo cov ntsiab lus kev ntxhov siab hauv cov qauv. Tempering kuj yog ib qho ntawm feem ntau siv txoj kev. Nws tuaj yeem tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sijhawm ua haujlwm xws li quenching. Cov kev ntxhov siab sab hauv tuaj yeem ua rau cov khoom siv tuaj yeem tawg thaum siv. Tom qab kev ntxhov siab sab hauv raug txo los ntawm tempering, lub toughness ntawm steel phaj yog txhim kho.

 

Kev tswj ntawm Phase Transformation txheej txheem: Kev tswj cov txheej txheem kev hloov pauv theem thaum lub caij txias ntawm cov hlau muaj kev cuam tshuam zoo rau cov tawv nqaij. Piv txwv li, los ntawm kev tswj cov cua txias, cov hlau tuaj yeem tsim cov qauv bainite. Cov qauv bainite muaj qhov sib npaug zoo ntawm toughness thiab lub zog. Nws cov acicular lossis plaub - zoo li microstructure tuaj yeem tiv thaiv kev nthuav tawm ntawm cov kab nrib pleb. Los ntawm kev tswj xyuas qhov txias txias thiab txhawb cov hlau kom tsim tau tus nqi tsim nyog ntawm bainite qauv, lub toughness ntawm CCS A550 steel phaj tuaj yeem txhim kho.

 

Yuav ua li cas lub Toughness ntawm CCS F500 Steel Phaj yog ua tiav

 

Nyob rau hauv cov nqe lus ntawm tshuaj muaj pes tsawg leeg

 

Lub luag haujlwm ntawm Alloying Elements: Rau CCS F500 steel phaj, alloying ntsiab kuj ua lub luag haujlwm tseem ceeb. Piv txwv li, qhov sib ntxiv ntawm molybdenum (Mo) tuaj yeem txhim kho cov tawv tawv ntawm cov hlau, ua rau cov hlau kom tau txais txheej txheej tawv tawv dua tom qab quenching. Qhov no yuav pab txhim kho toughness los ntawm cov kev kho mob tom qab tsim nyog xws li tempering thaum ua kom muaj zog. Lub caij no, chromium (Cr) tuaj yeem txhim kho cov kev ua haujlwm antioxidant thiab corrosion kuj ntawm cov hlau thiab tseem pab txhim kho toughness rau qee yam. Nws tuaj yeem tsim cov carbide ruaj khov nrog cov pa roj carbon hauv cov hlau. Cov carbides no ua lub luag haujlwm hauv kev ua kom cov nplej zom thiab tawg ua kom muaj zog hauv microstructure, tsis ncaj qha txhim kho cov tawv tawv ntawm cov hlau.

 

Qhov tseem ceeb ntawm Impurity Control: Ib yam li CCS A550 steel phaj, CCS F500 steel phaj kuj yuav tsum tau nruj me ntsis tswj cov impurity ntsiab. Cov ntsiab lus qis ntawm sulfur thiab phosphorus tuaj yeem txo qhov tsim ntawm kev sib koom ua ke, zam kev pib thiab nthuav tawm ntawm cov kab nrib pleb tshwm sim los ntawm kev sib koom ua ke, thiab yog li ua kom zoo toughness. Advanced steel - kev siv thev naus laus zis, xws li lub tshuab nqus tsev degassing, tuaj yeem siv los tshem tawm cov khoom tsis zoo no.

Txhais tau hais tias ntawm Microstructure Regulation

 

Thaum tshav kub kub tshwj xeeb - kev kho mob: CCS F500 steel phaj tuaj yeem txais kev quenching - tempering sib xyaw ua ke cua sov - txheej txheem kev kho mob los txhim kho toughness. Cov txheej txheem quenching tuaj yeem ua rau cov hlau kom tau txais lub zog ntau dua, tab sis nws tseem yuav ua rau muaj kev ntxhov siab ntau hauv tib lub sijhawm. Los ntawm kev kho kom haum raws sijhawm, kev ntxhov siab sab hauv tuaj yeem raug tshem tawm, thiab microstructure ntawm cov hlau tuaj yeem ua kom zoo dua. Thaum lub sij hawm tempering, carbon atoms yuav redistribute nyob rau hauv steel matrix los tsim ib tug ruaj khov microstructure, yog li txhim kho toughness.

 

Tswj ntawm Microstructure Morphology: Tswj lub microstructure morphology ntawm hlau yog qhov tseem ceeb heev rau kev txhim kho toughness. Piv txwv li, los ntawm cov txheej txheem tsim nyog, CCS F500 steel phaj tuaj yeem tsim ib qho kev faib ua feem ntawm martensite - austenite (M - A). Cov khoom no muaj qhov zoo toughness thiab yas deformation muaj peev xwm. Thaum cov khoom siv nyob rau hauv lub zog sab nraud, nws tuaj yeem nqus tau lub zog los ntawm nws tus kheej deformation thiab tiv thaiv kev nthuav tawm sai ntawm cov kab nrib pleb, yog li ua tiav cov tawv tawv zoo.
