Zas cam khwb cia hlau, uas yog sawv cev rau ib pawg ntawm cov cam khwb cia hlau, tseem hu ua nodular hlau. Nodular cam khwb cia hlau tau txais nodular graphite los ntawm spheroidization thiab inoculation kho, uas ua kom zoo dua cov neeg kho tshuab zog ntawm covcasting qhov chaw, tshwj xeeb tshaj yog cov yas thiab toughness, yog li kom tau txais lub zog siab dua li carbon hlau.
Zas hlau tsis yog cov khoom siv ib zaug xwb tab sis yog ib feem ntawm ib pawg ntawm cov ntaub ntawv uas tuaj yeem tsim kom muaj cov khoom sib txawv los ntawm kev tswj hwm ntawm microstructure. Cov cwj pwm uas nquag txhais ntawm cov pab pawg ntawm cov ntaub ntawv no yog cov duab ntawm graphite. Hauv cov kua roj voos caj dab, lub graphite yog nyob rau hauv daim ntawv ntawm nodules ntau dua li flakes raws li nws yog nyob rau hauv grey hlau. Lub ntsej muag zoo ntawm cov plaub ya ri ntawm graphite tsim cov ntsiab lus kev nyuaj siab tsis pub dhau ntawm cov hlau ua kom sib npaug thiab cov duab sib npaug ntawm cov nodules tsawg dua, yog li inhibiting kev tsim cov nrib pleb thiab muab cov kev txhim kho ductility uas muab cov alloy nws lub npe.
Nodular cam khwb cia hlau tau loj hlob sai mus rau hauv cov khoom siv cam hlau cam thib ob tsuas yog rau grey cam khwb cia hlau thiab siv dav. Cov thiaj li hu ua "hloov hlau rau hlau" feem ntau yog hais txog hlau ductile. Zas hlau feem ntau yog siv los tsim qhov chaw rau crankshafts thiab camshafts rau tsheb, tsheb laij teb, thiab sab hauv kev sib xyaw cav, nrog rau cov khoom nruab nrab-siab rau cov tshuab dav dav.
