Sib tsoo ntiv nplhaib rau zeb
Qhov zoo heev
Cov coj tsis kam ntawm cov av zeb txuas ntxiv yog qhov tseem ceeb. Feem ntau, ntau tus neeg xav tias cov khoom nyuaj, ntau lub ntsej muag tau tshaj tawm tias lawv cov kev pom zoo tshaj li 30%, thiab HRC hardness ncav cuag 63-65. Txawm li cas los xij, ntau dua dispersed faib tawm, qhov ntau dua qhov tshwm sim ntawm kev sib nraus ntawm lub interface ntawm matrix thiab cov carbides, thiab qhov tshwm sim ntawm pob txha no tseem loj dua. Thiab cov khoom nyuab dua, qhov nyuaj nws yog txiav. Yog li ntawd, ua kom muaj kev hnav cov nplhaib sib tsoo thiab ruaj khov ntiv nplhaib tsis yooj yim. Sib tsoo ntiv nplhaib tsuas yog siv ob hom ntaub ntawv hauv qab no.
65mn (65 Manganese): Cov ntaub ntawv no tuaj yeem txhim kho lub nplhaib sib tsoo. Nws yog muaj cov yam ntxwv ntawm kev tawv tawv siab, zoo heev coj tsis kam thiab zoo nkauj tiv thaiv, nws yog feem ntau yog siv nyob rau hauv lub tiaj ua teb uas cov khoom yuav tsum tshem tawm cov hlau. Cov hnav tsis kam thiab cov tawv tuaj yeem txhim kho kom zoo los ntawm kev coj ua thiab kev kho kom sov sov.
MN13 (13 mangananese): Lub durability ntawm cov nplhaib sib tsoo cam khwb nrog MN13 tau raug txhim kho piv nrog 65mn. Lub castings ntawm cov khoom no tau kho nrog dej tawv tom qab pouring, lub castings muaj ntau dua tensile lub zog, kev sib cav sib ceg tom qab dej sib tsoo ntau dua. Thaum raug rau kev cuam tshuam loj thiab muaj zog deformation thaum khiav ua haujlwm zoo heev, yog tias nws yuav tsum tau ua kom cov menyuam ua haujlwm zoo heev
