Caij nplooj ntoos hlav chim steel hlau txheej txheem

Lwm hom carbon caij nplooj ntoos hlav steel hlau yog martensite reinforced steel hlau, tseem hu ua roj quenched tempered steel hlau.Thaum qhov loj ntawm cov hlau hlau me me (φ ≤2.0 hli), lub zog indexes ntawm cov roj-quenched thiab tempered steel hlau yog qis dua qhov txias-draw steel hlau tom qab Soxhlet kho.Thaum qhov loj ntawm cov hlau hlau loj (φ ≥6.0 hli), nws tsis tuaj yeem tau txais qhov ntsuas lub zog yuav tsum tau ua los ntawm kev siv thaj tsam loj txo qis, cov roj-quenched thiab tempered steel hlau tuaj yeem tau txais kev ua tau zoo dua li cov hlau txias txias. tsuas yog tias nws yog tag nrho quenched.Raws li tib lub zog tensile, martensite reinforced steel hlau muaj siab dua elastic txwv tshaj qhov txias deformation reinforced steel hlau.Lub microstructure ntawm txias-draw steel hlau yog fibrous thiab anisotropic.Lub microstructure ntawm roj-quenched thiab tempered steel hlau yog homogeneous martensite thiab yuav luag isotropic.Nyob rau tib lub sijhawm, kev so tsis kam ntawm cov roj-quenched thiab tempered steel hlau yog zoo dua li cov hlau txias txias, thiab qhov kev pabcuam kub (150 ~ 190 ° C) kuj siab dua li cov hlau txias txias ( ≤120 ° C).Loj-loj roj-quenched thiab tempered steel hlau muaj ib tug nyiam los hloov txias-draw steel hlau.
