1.Dab tsi yog cov ntsiab lus tseem ceeb thiab kev ua tau zoo ntawm interstitial steel (IF steel)?
Ntxiv cov nqi tsim nyog ntawm titanium (Ti) lossis niobium (Nb) rau ultra- cov pa roj carbon tsawg ua tiav kho cov pa roj carbon thiab nitrogen interstitial atoms hauv cov hlau rau hauv carbonitrides, kom tsis muaj cov atom dawb interstitial hauv cov hlau.
Formability zoo heev, tsis muaj kev laus, tsis muaj yield plateau, haum rau stamping qhov chaw nrog cov duab nyuaj thiab tshwj xeeb tshaj yog cov kev cai nruj heev.
2.Dab tsi yog lub hauv paus ntsiab lus thiab kev ua tau zoo ntawm cov uas tsis yog -aging ultra- sib sib zog nqus nqus nqus hlau?
Lub npe raws li cov qauv ntawm cov tuam txhab xws li Baosteel, nws cov khoom zoo ib yam li IF steel, nthuav tawm cov khoom tsis yog - laus thiab kev ua haujlwm zoo heev.
BSUFD nthuav tawm cov kev ua haujlwm zoo tshaj plaws, nrog rau kev sib sib zog nqus zoo tshaj - kos duab thiab kos duab, txo tus lej ntawm cov ntawv hla dhau.
3.Dab tsi yog lub hauv paus ntsiab lus thiab kev ua tau zoo ntawm kev laus -tiv taus qis- tawm los steel?
Los ntawm kev tswj cov txheej txheem metallurgical, cov khoom muaj kev tiv thaiv zoo rau kev laus thiab tsis tshua muaj cov kab slippage thaum lub sij hawm stamping.
Nws muaj kev ua haujlwm zoo dua qub dua li cov pa roj carbon tsawg zoo tib yam thiab tsis tshua muaj siab rau tensile strain marks (slip kab).
4.Dab tsi yog lub hauv paus ntsiab lus thiab kev ua tau zoo ntawm cov hlau siv rau kev stamping?
Txawm hais tias qee qhov kev ua haujlwm siab -kev ua haujlwm qis- carbon steels tsis tshem tawm cov atoms interstitial, lawv tseem tuaj yeem ua rau muaj kev tiv thaiv zoo rau kev laus hauv kev siv tswv yim los ntawm kev tswj cov txheej txheem.
Nws yog qhov tsim nyog rau kev stamping thiab tsim, thiab nyob rau hauv ib txwm cia thiab siv cov xwm txheej, qhov tshwm sim ntawm kev laus tsis pom tseeb.
5.Txhua yam, nws zoo li cas?
Yog tias koj xav tau tiag tiag "timeless" steel, txhais tau hais tias koj tsis tas yuav txhawj xeeb txog cov txiaj ntsig siab thiab tensile strain cim tsis hais lub sijhawm cia lossis ua ntej ua haujlwm, ces IF steel (xws li DC04 thiab DC06) thiab Baosteel's BUSD thiab BUFD yog qhov kev xaiv zoo tshaj. Lawv feem ntau yog siv rau hauv daim ntawv thov xws li tsheb vaj huam sib luag thiab cov khoom siv vaj tsev nyob qhov twg qhov zoo ntawm qhov chaw thiab cov qauv tsim muaj siab heev.
