Khoom Description
Kev tswj hwm impurity muaj cov kev cuam tshuam tseem ceeb hauv qab no rau qhov toughness thiab vuam kev ua tau zoo ntawm high-strength steel:
I. Kev cuam tshuam rau qhov tawv
Txo cov kab nrib pleb tawm tsam: Thaum cov ntsiab lus impurity nyob rau hauv cov hlau muaj zog muaj zog kuj siab, microscopic defects xws li inclusions thiab segregation yuav tsim nyob rau hauv cov hlau. Cov teeb meem no yuav dhau los ua qhov chaw ntawm kev pib tawg thiab nthuav tawm, txo cov kab nrib pleb tawm tsam ntawm cov hlau thiab yog li txo qhov toughness ntawm cov hlau. Piv txwv li, impurity cov ntsiab lus xws li sulfur (S) thiab phosphorus (P) yuav tsim nkig inclusions, uas yog nquag ua rau tawg thiab txo cov toughness ntawm cov hlau thaum muaj kev ntxhov siab.
cuam tshuam cov qauv nplej: Cov ntsiab lus impurity tseem yuav cuam tshuam cov qauv nplej ntawm cov hlau muaj zog. Qee cov ntsiab lus impurity yuav txhawb cov qoob loo loj hlob thiab ua rau cov nplej ua ntxhib, yog li txo cov tawv tawv ntawm cov hlau. Los ntawm kev tswj hwm cov ntsiab lus impurity, cov nplej tuaj yeem ua kom zoo dua qub thiab lub zog ntawm cov hlau tuaj yeem txhim kho. Piv txwv li, cov khoom xws li txhuas (Al) thiab titanium (Ti) tuaj yeem tsim cov nitrides zoo thiab carbides los tiv thaiv kev loj hlob ntawm cov qoob loo thiab yog li txhim kho cov tawv tawv ntawm cov hlau.
Hloov cov theem hloov pauv tus cwj pwm: Cov ntsiab lus tsis huv kuj tuaj yeem hloov pauv theem hloov tus cwj pwm ntawm cov hlau muaj zog thiab cuam tshuam rau cov qauv thiab cov khoom ntawm cov hlau. Piv txwv li, cov ntsiab lus xws li carbon (C) thiab manganese (Mn) yuav cuam tshuam rau martensite transformation kub thiab transformation ceev ntawm hlau, yog li cuam tshuam rau lub zog thiab toughness ntawm cov hlau. Los ntawm kev tswj hwm cov ntsiab lus ntawm impurity cov ntsiab lus, theem kev hloov pauv tus cwj pwm ntawm cov hlau tuaj yeem ua kom zoo dua qub thiab lub zog ntawm cov hlau tuaj yeem txhim kho.

II. Kev cuam tshuam rau kev ua haujlwm vuam
Tsim cov kab nrib pleb: Cov ntsiab lus tsis huv hauv cov hlau muaj zog yuav muaj kev cuam tshuam tsis zoo thaum lub sij hawm vuam txheej txheem thiab ua rau kom qhov rhiab heev ntawm vuam tawg. Piv txwv li, impurity ntsiab xws li sulfur (S) thiab phosphorus (P) yuav txo qhov melting point ntawm cov hlau, ua rau segregation nyob rau hauv lub vuam hlau thaum lub sij hawm solidification thiab tsim tsawg-melting-point eutectics, ua rau muaj kev pheej hmoo ntawm welding tawg. Tsis tas li ntawd, cov khoom siv hydrogen (H) tseem yuav nkag mus rau cov hlau thaum lub sij hawm vuam, tsim cov kab nrib pleb uas ua rau cov kab nrib pleb thiab txo qhov kev ua haujlwm ntawm cov hlau.
Muaj feem cuam tshuam rau kev ua haujlwm ntawm thaj chaw uas muaj kev kub ntxhov: Thaum lub sij hawm vuam txheej txheem, lub tshav kub cuam tshuam ntawm cov hlau muaj zog yuav cuam tshuam los ntawm qhov kub thiab txias, uas ua rau muaj kev hloov pauv ntawm cov qauv thiab kev ua haujlwm. Cov ntsiab lus impurity yuav cuam tshuam rau kev hloov pauv ntawm lub koom haum thiab kev ua haujlwm ntawm thaj chaw muaj kev kub ntxhov thiab txo qhov kev ua haujlwm ntawm cov hlau. Piv txwv li, cov ntsiab lus xws li cov pa roj carbon (C) thiab manganese (Mn) yuav ua rau cov tawv tawv ntawm thaj chaw muaj kev kub ntxhov, ua rau cov hlau ua rau cov kab mob txias tom qab vuam. Los ntawm kev tswj hwm cov ntsiab lus impurity, lub hardness ntawm thaj tsam kub-tshuaj yuav raug txo kom tsawg thiab cov vuam kev ua tau zoo ntawm cov hlau tuaj yeem txhim kho.
Txo qhov toughness ntawm weld hlau: impurity cov ntsiab lus tseem yuav txo qhov toughness ntawm weld hlau thiab cuam tshuam rau kev ua tau zoo ntawm cov pob qij txha. Piv txwv li, impurity ntsiab xws li oxygen (O) thiab nitrogen (N) yuav tsim oxide thiab nitride inclusions nyob rau hauv cov hlau weld, txo cov toughness thiab plasticity ntawm cov hlau weld. Los ntawm kev siv cov txheej txheem vuam zoo heev thiab cov khoom siv vuam, kev nkag ntawm cov khoom tsis huv tuaj yeem raug txo thiab qhov toughness thiab vuam kev ua tau zoo ntawm cov hlau vuam tuaj yeem txhim kho.
