Qhov txawv ntawm cov hlau tiaj tus thiab cov hlau carbon yog dab tsi?

hlau thiab cov hlau carbon.

Txawm hais tias ob qho tib si siv rau cov hom phiaj zoo sib xws, muaj ntau qhov sib txawv tseem ceeb ntawm ob qho uas ua rau lawv zoo dua rau cov ntawv thov sib txawv.

Cov hlau carbon yog dab tsi?
Cov hlau carbon yog ib hom hlau uas muaj cov pa roj carbon ua cov khoom tseem ceeb, nrog rau lwm cov ntsiab lus muaj nyob rau hauv cov khoom me me. Cov hlau no feem ntau siv rau hauv kev tsim ntau yam khoom thiab cov qauv vim nws lub zog siab thiab tus nqi qis.

Cov hlau carbon tuaj yeem muab faib ua ntau qib raws li nws cov tshuaj lom neeg thiab cov khoom siv kho tshuab, xws li cov hlau carbon qis (hlau me me), hlau carbon nruab nrab, hlau carbon siab thiab hlau carbon siab heev. Txhua qib muaj nws tus kheej siv thiab daim ntawv thov, nyob ntawm cov yam ntxwv xav tau ntawm cov khoom kawg.

Cov hom hlau carbon
Muaj ntau hom hlau carbon, txhua hom muaj cov yam ntxwv thiab kev siv tshwj xeeb. Cov hom no suav nrog:

Cov hlau carbon tsawg
Kuj hu ua "mild steel," hom hlau no yooj yim dua thiab yooj yim dua rau kev ua duab, tsim thiab vuam piv rau lwm hom hlau carbon. Qhov no ua rau cov hlau mild yog qhov kev xaiv nrov dua li cov hlau carbon siab dua thaum nws los txog rau kev tsim kho thiab kev tsim khoom.

Cov hlau carbon nruab nrab
Muaj cov pa roj carbon 0.3% txog 0.6%, ua rau nws muaj zog thiab tawv dua li cov hlau uas muaj carbon tsawg tab sis kuj tawg yooj yim dua. Nws feem ntau siv rau hauv cov ntawv thov uas xav tau ob qho tib si lub zog thiab kev ywj pheej, xws li cov khoom siv tshuab, cov khoom siv tsheb thiab cov thav duab tsev.

Cov hlau carbon siab

Cov hlau uas muaj carbon ntau muaj cov ntsiab lus carbon ntawm 0.6% txog 1.5% thiab paub txog nws lub zog thiab qhov tawv, tab sis cov hlau uas muaj carbon ntau tseem yooj yim dua li cov hlau uas muaj carbon nruab nrab. Cov hlau uas muaj carbon ntau yog siv rau hauv cov ntawv thov uas xav tau lub zog siab xws li cov hniav riam, cov cuab yeej tes thiab cov caij nplooj ntoos hlav.
