I. Kev Taw Qhia
Lub Rooj Sib Tham European Lub Cev Lub Cev (ECB Conference) faib cov tsheb hlau daim hlau raws li cov ntaub so ntswg metallurgical, faib cov hlau rau hauv cov hlau me me, cov hlau muaj zog, cov hlau siab siab siab thiab ultra-high-strength steel.
Advanced High Strength Steels (AHSS) yog cov khoom siv nrog ntau theem qauv. Qhov yuav tsum tau muaj tshuaj lom neeg muaj pes tsawg leeg thiab ntau theem microstructure tau ua tiav los ntawm kev tswj xyuas nruj ntawm cov cua sov thiab cua txias, thiab ntau yam kev txhawb zog siv los ua kom muaj zog sib txawv, Ductility, toughness thiab qaug zog zog.
2. Kev ua tau zoo
Yav dhau los, steel nrog lub zog tensile tshaj 550 MPa tuaj yeem raug faib ua cov hlau siab siab, thaum cov hlau uas muaj lub zog tensile tshaj 780 MPa tau muab cais ua cov hlau muaj zog ultra-high-strength. Txawm li cas los xij, tam sim no qhov tsawg kawg nkaus tensile lub zog ntawm ntau theem siab siab-siab steel yog 440 Mpa, yog li siv lub zog raws li qhov kev ntsuas rau kev txhais cov qib siab zog steel tsis siv tau lawm. Advanced high-strength steel nrog lub zog tensile ntawm 1000 MPa kuj feem ntau hu ua 1Gpa steel. Thib peb-tiam qib siab zog steels yuav tsum ua kom tiav qhov sib npaug lossis kev ua tau zoo dua ntawm cov nqi qis.
