Kev siv dav dav
Nrog nws cov khoom zoo ntawm lub cev thiab cov txiaj ntsig tseem ceeb ntawm kev lag luam,hlau hlauyog maj mam dhau los ua cov khoom ntawm kev xaiv nyob rau hauv ntau qhov kev lag luam, dav hloov cov khoom siv xws li forged steel, stamped steel, weldments, malleable cam khwb cia hlau,grey cam khwb cia hlauthiab cam khwb cia hlau. Hauv Tebchaws Meskas, qhov sib txawv no tshwj xeeb yog pom tseeb. Ductile hlau tau tuav ib feem tseem ceeb ntawm kev ua lag luam thiab tau ua tiav qhov sib txawv ntawm cov khoom siv tau hais los saum toj no, ua kom pom nws qhov kev thov tsis sib xws thiab kev sib tw ua lag luam.

Kev txheeb xyuas cov khoom muaj pes tsawg leeg
Los ntawm qhov kev xav ntawm cov qauv tsim, kev tsim cov khoom siv hlau yog ua los ntawm ferrite matrix, suav txog 60% ntawm tag nrho cov khoom tsim tawm, thaum pearlite matrix ua raws li tom qab thiab nyob hauv ib qho chaw. Tsis tas li ntawd, qhov sib xyaw matrix ntawm ferrite thiab pearlite kuj suav nrog feem ntau. Qhov peb ua ke suav txog yuav luag 95% ntawm tag nrho cov khoom siv hlau, qhia txog qhov tseem ceeb ntawm ob lub matrices hauv kev tsim cov hlau ductile.
Zoo heev mechanical zog tsom xam
Qhov laj thawj tseem ceeb vim li cas cov hlau nplaum tuaj yeem sawv ntawm ntau cov ntaub ntawv yog nyob rau hauv nws cov khoom siv tshwj xeeb. Nws tsis muaj qhov taw tes tawm hauv qhov kev xav ib txwm muaj, thiab qhov kev ntxhov siab-txoj kab nkhaus qhia cov yam ntxwv tsis tu ncua gradient saum toj kawg nkaus qhov kev txwv. Cov yam ntxwv no tshwm sim los ntawm tus cwj pwm tshwj xeeb ntawm cov pob graphite nyob rau hauv kev ntxhov siab: thaum qhov kev ntxhov siab tshaj qhov kev txwv elastic, txawm hais tias cov pob graphite zoo li yog ib feem ntawm cov matrix, lawv yeej tsis deform, tsim qhov khoob ntawm qhov ntev, uas ua rau lub ntim nthuav dav. , thiab qhov kev nthuav dav no tsis tuaj yeem Compensated los ntawm lateral compression.
Kev sib piv nrog lwm cov ntaub ntawv
Grey cam khwb cia hlau: Kev lig kev cai, tsuas yog lub zog tensile yog siv los ua qhov taw qhia kev ua tau zoo, thiab qib siab tshaj plaws tau txwv lub zog tensile (tsuas yog 350 MPa). Nyob rau hauv sib piv, ductile hlau qhia tau hais tias qhov zoo ntawm ob qho tib si lub zog thiab plasticity.
Malleable cam khwb cia hlau: Txawm hais tias nws muaj plasticity indicators, Txawm hais tias nws yog dub-core, pearlite los yog dawb-core malleable hlau, nws cov khoom siv txhua yam tsis zoo li cov hlau.
Cam khwb cia hlau thiab cov qauv hlau: Txawm hais tias nws muaj kev ua tau zoo hauv kev ua haujlwm tom qab tawg ntho thiab cuam tshuam, lub zog tawm los tsis zoo li cov hlau nplaum, ntxiv qhov tseem ceeb ntawm qhov zoo ntawm cov hlau hlau hauv cov ntawv tshwj xeeb.
