Ductile hlau, tseem hu ua nodular cam khwb cia hlau los yog spheroidal graphite hlau, yog ib hom cam khwb cia hlau alloy uas tau txhim kho ductility thiab toughness vim muaj spherical graphite nodules. Cov khoom siv hlau feem ntau yog siv rau hauv ntau daim ntawv thov thoob plaws kev lag luam xws li tsheb, roj thiab roj, khoom siv, thiab kev ua liaj ua teb machinery. Feem ntau ntawmtsheb chassis qhov chawthiabncua qhov chawyog ductile hlau. Nws muab lub zog, durability, cuam tshuam tsis kam, corrosion kuj thiab nqi-zoo rau cov khoom siv fabrication.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv hlau yog lawv lub zog siab thiab ua haujlwm ntev. Lawv muaj peev xwm tiv taus cov khoom hnyav thiab hnyav ib puag ncig, ua rau lawv zoo tagnrho rau kev siv hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv siab hnav, corrosion, thiab cuam tshuam.
Tsis tas li ntawd, cov khoom siv hlau nplaum muaj cov khoom siv tau zoo thiab yooj yim rau cam khwb cia, uas ua rau lawv raug nqi zoo piv rau lwm cov ntaub ntawv xws li hlau lossis txhuas. Lawv kuj yog customizable heev, ua rau nws muaj peev xwm los tsim qhov chaw nrog complex duab thiab designs.
Cov khoom siv hlau tau dhau los ua qhov kev xaiv nrov rau cov ntawv thov uas yuav tsum muaj lub zog siab, ua haujlwm ntev, thiab tus nqi siv tau zoo, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas siv cov cuab yeej hnyav thiab tshuab.
Cov txheej txheem hlau ductile, tseem hu ua nodular cam khwb cia hlau txheej txheem los yog spheroidal graphite hlau txheej txheem, koom nrog ntxiv ntawm magnesium los yog lwm yam ntaub ntawv zoo sib xws rau molten cam khwb cia hlau. Qhov no tsim nodules ntawm graphite nyob rau hauv cov hlau, uas muab nws cov yam ntxwv tshwj xeeb.
Cov txheej txheem hlau ductile feem ntau pib nrog lub melting ntawm cov hlau nyob rau hauv lub cub tawg, ua raws li qhov sib ntxiv ntawm ib tug meej npaum li cas ntawm magnesium. Magnesium reacts nrog cov pa roj carbon monoxide nyob rau hauv cov hlau, ua rau tsim cov graphite nodules uas yog spherical nyob rau hauv cov duab.
Tom qab ntawd cov hlau molten yog poured rau hauv pwm thiab tso cai rau txias thiab solidify. Thaum cov hlau cam khwb cia txias thiab solidifies, nws raug tshem tawm los ntawm pwm thiab ua tiav cov txheej txheem tiav kom tshem tawm cov khoom siv ntau dhau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm covhlau hlautxheej txheem yog hais tias nws tso cai rau cov creation ntawm complex duab thiab designs. Tsis tas li ntawd, cov khoom siv hlau tuaj yeem tsim tau ntawm tus nqi qis dua li lwm cov ntaub ntawv xws li steel, ua cov txheej txheem no yog qhov kev xaiv nrov hauv ntau yam kev lag luam.
