Iron vs Cam khwb cia hlau
Hlau thiab cam khwb cia hlau qhia ntau qhov sib txawv ntawm lawv nyob rau hauv cov nqe lus ntawm lawv cov khoom thiab xwm. Cam khwb cia hlau feem ntau yog hais txog grey hlau. Cam khwb cia hlau yog feem ntau ntawm ob hom, uas yog, dawb cam khwb cia hlau thiab grey cam khwb cia hlau. Dawb cam khwb cia hlau yog li lub npe vim hais tias ntawm qhov tseeb hais tias nws nto yog dawb thaum tawg. Ntawm qhov tod tes, grey cam khwb cia hlau muaj npe tom qab nws cov qauv grey tawg.
Iron ntawm qhov tod tes yog cov hlau ntau tshaj plaws uas muaj nyob rau hauv daim ntawv ntshiab nyob rau hauv sab hauv thiab sab nraud ntawm lub ntiaj teb lub ntiaj teb. Nws tseem raug suav hais tias yog cov hlau ntau tshaj plaub uas muaj nyob hauv lub ntiaj teb daim tawv nqaij.
Ib qho ntawm qhov sib txawv ntawm cov hlau thiab cam khwb cia hlau yog cov hlau yog nyob rau hauv daim ntawv ntshiab whereas cam khwb cia hlau yog hlau alloyed. Nws yog alloyed nrog cov ntsiab lus xws li silicon thiab carbon. Qhov no yog vim li cas vim li cas hlau muaju yog mos thiab cam khwb cia hlau crystals yog nkig.
Vim tias cam khwb cia hlau yog alloyed nrog lwm cov khoom, cov khoom ntawm cov hlau alloyed tau txuas nrog cov hlau dhau lawm thiab yog li cov khoom ntawm cov hlau cam tsis sib xws. Ntawm txhais tes cov khoom ntawm hlau zoo ib yam vim qhov tseeb tias nws yog ib qho hlau ntshiab.
Cov hlau ntawm cov hlau ua rau cov txheej txheem oxidization thaum raug huab cua. Ntawm qhov tod tes, alloyed cam khwb cia hlau tsis dhau cov txheej txheem ntawm oxidization thaum raug huab cua. Hlau tau xeb heev thaum raug cov dej noo. Ntawm qhov tod tes, cam khwb cia hlau tsis raug tsim los ntawm xeb thaum raug dej.
Nws yog qhov nthuav kom nco ntsoov tias cam khwb cia hlau tuaj yeem hloov mus rau ntau yam khoom xws li cov hlau nplaum, hlau grey, hlau tsis muaj hlau, hlau dawb thiab hlau wrought.
