Cam khwb cia hlau yog cov hlau-carbon cam khwb cia hlau nrog lwm cov khoom uas yog tsim los ntawm remelting npua hlau, seem, thiab lwm yam ntxiv. Rau kev sib txawv ntawm cov hlau thiab cam khwb cia hlau, cam khwb cia hlau yog txhais tau tias yog cov cam khwb cia hlau nrog cov ntsiab lus carbon (min 2.03%) uas ua kom cov solidification ntawm theem kawg nrog kev hloov pauv eutectic.
Raws li kev txheeb xyuas tshuaj, cam khwb cia hlau tuaj yeem yog non-alloyed lossis alloyed. Qhov ntau ntawm cov hlau alloyed yog dav dua, thiab lawv muaj ntau dua ntawm cov khoom sib xws, xws li silicon thiab manganese, lossis tshwj xeeb ntxiv, xws li npib tsib xee, chromium, aluminium, molybdenum, tungsten, tooj liab, vana-dium, titanium, ntxiv rau. lwm tus. Feem ntau hais lus, cam khwb cia hlau tuaj yeem muab faib ua grey hlau, ducitle hlau (nodular hlau), dawb cam khwb cia hlau, compacted graphite hlau thiab malleable cam khwb cia hlau.
Ductile cam khwb cia hlau, uas yog sawv cev rau ib pawg ntawm cam khwb cia hlau, kuj hu ua nodular hlau. Nodular cam khwb cia hlau tau txais nodular graphite los ntawm spheroidization thiab inoculation kev kho mob, uas zoo txhim kho cov neeg kho tshuab zog ntawm cov cam khwb cia hlau, tshwj xeeb tshaj yog cov yas thiab toughness, thiaj li yuav tau txais lub zog siab dua carbon steel.
Hlau cam khwb cia hlau castingsmuaj kev poob siab zoo dua li carbon steel, thaum carbon steel castings muaj qhov zoo dua weldability. Thiab rau qee qhov, cov ductile iorn castings tuaj yeem muaj qee qhov kev ua yeeb yam ntawm kev hnav thiab xeb. Yog li cov hlau nplaum hlau tuaj yeem siv rau qee lub twj tso kua mis lossis cov khoom siv dej. Txawm li cas los xij, peb tseem yuav tsum tau ceev faj tiv thaiv lawv ntawm kev hnav thiab xeb.
Ductile hlau tsis yog ib qho khoom siv xwb tab sis yog ib feem ntawm cov khoom siv uas tuaj yeem tsim kom muaj ntau yam khoom los ntawm kev tswj hwm ntawm microstructure. Lub ntsiab lus txhais cov yam ntxwv ntawm pawg ntawm cov ntaub ntawv no yog cov duab ntawm graphite. Hauv cov hlau nplaum, cov graphite yog nyob rau hauv daim ntawv ntawm nodules es tsis yog flakes li nws yog nyob rau hauv grey hlau. Lub ntsej muag zoo nkauj ntawm cov flakes ntawm graphite tsim cov ntsiab lus kev ntxhov siab nyob rau hauv cov hlau matrix thiab cov duab sib npaug ntawm cov nodules tsawg dua, yog li inhibiting kev tsim cov kab nrib pleb thiab muab cov ductility zoo dua uas muab cov hlau nws lub npe.
