Los ntawm kev siv cov hlau muaj zog, ntau yam khoom ntawm lub cev ntawm lub tsheb tuaj yeem ua thinned yam tsis muaj zog. Hauv Tebchaws Europe thiab Tebchaws Meskas, nws tau pom zoo tias los ntawm daim ntawv thov ntawm 600MPa / 40% rau 1600MPa / 20% high-strength steel nyob rau hauv lub tsheb lub cev qauv, lub luj ntawm lub tsheb lub cev yuav txo tau los ntawm tsawg kawg yog {{6 } } %, uas coj lub cib fim rau txoj kev loj hlob ntawm ntau yam series ntawm high-strength steels nyob rau hauv no kev ua tau zoo ntau yam.
Hais txog kev txhim kho tom ntej thiab kev tshawb fawb cov ntsiab lus ntawm automotive steel, International NSF Organization (National Steel Fabrication), US Department of Energy (DOE), American AISI Steel Institute (American Iron and Steel Institute) thiab A/SP (Auto /Steel Partnership), tshaj tawm cov kev tshawb fawb hauv qab no hauv cov tsev kawm ntawv qib siab, cov koom haum tshawb fawb thiab lwm lub koom haum
Microstructure thiab mechanical zog ntawm advanced high-strength steels;
Cov txheej txheem carbon diffusion nyob rau hauv cov qib siab zog steel;
Particle loj thiab cuam tshuam cuam tshuam ntawm cov qib siab zog steel:
Nano-acicular ferrite hom dual-theem steel nyob rau hauv advanced high-strength steel;
Siab zog thiab siab yas bainitic steel:
Formability thiab springback tus cwj pwm ntawm advanced high-strength steel:
Cov qauv sib xws rau cov qib siab zog steel.
Kev thov yuav txhawb nqa kev nce qib ntawm cov thev naus laus zis ntsig txog, thiab kev siv thev naus laus zis tseem yuav txhawb nqa qhov kev thov nce ntxiv. Kev sib piv dav dav ntawm lub teeb yuag yuav txhawb nqa kev nce qib ntawm kev siv thev naus laus zis hauv kev lag luam steel, yog li tsim cov xwm txheej rau daim ntawv thov ntawm cov ntawv hlau ntau dua. Txoj kev loj hlob tom ntej ntawmautomotive hlau, los yog qhov zoo tshaj plaws tsheb hlau phaj cov khoom siv nyob rau niaj hnub no, yuav tsum muaj cov hauv qab no: cov pa roj carbon tsawg (siab weldability), tus nqi qis (tsis tshua muaj alloy ntxiv), siab formability, Yooj yim rau dhos thiab kho. Niaj hnub no, ntau yam ntawm automotive high-strength steels feem ntau muaj qee qhov kev txwv, xws li qhov sib txawv loj hauv kev sib xyaw thiab qhov tsis zoo ntawm qhov chaw, uas txhua tus coj qee qhov teeb meem rau kev pleev xim zaum kawg. Nyob rau hauv lub neej yav tom ntej, kev soj ntsuam ntawm ntau yam ntaub ntawv yuav tsum tau txiav txim siab los ntawm kev xav ntawm tag nrho cov txheej txheem, thiaj li hais tias cov khoom zoo thiab cov tswv yim tsim thiab tsim.
