Hauv kev lag luam lag luam, cov khoom ntawm cov hlau yog qhov tseem ceeb tshaj plaws. Lub hardness, brittleness, kev muaj zog thiab lub zog ntawm cov hniav muaj qhov cuam tshuam ncaj qha rau nws cov kev txiav tawm, kev pabcuam lub neej thiab daim ntawv thov kev pabcuam. Ntawm cov cwj pwm no, kev sib txheeb ntawm brittleness thiab hardness yog ntawm kev txaus siab tshwj xeeb. Yog li, ua kom loj dua yog tias cov hlau yog qhov nyuaj lossis ntau dua?
Brittleness, raws li lub cev cov cuab yeej ntawm cov hlau, qhia txog qhov nyiam ntawm cov khoom kom tawg yooj yim thaum raug rau sab nraud. Tsuas yog muab tso, cov hlau nrog cov loj brittleness muaj ntau dua yuav tawg thaum raug rau kev cuam tshuam lossis siab. Qhov no zoo ib yam li cov ntaub ntawv loj heev xws li cam khwb cia hlau, uas feem ntau pom hauv peb lub neej txhua hnub, thiab nyiam tawg tau yooj yim ib zaug lawv tau raug rau sab nraud.
Txawm li cas los xij, yog hais txog qhov muaj peev xwm ntawm cov khoom siv los tiv thaiv ib qho khoom tawv nias rau hauv nws qhov chaw. Nws yog ib qho ntawm cov khoom ua tau zoo tshaj plaws ntawm cov ntaub ntawv me me me ntawm cov khoom lag luam xws li HRC, HV thiab HB. Nyob rau hauv lub teb ntawm kev muaj cua muaj li, theem ntawm hardness ncaj qha txiav txim siab ncaj qha rau kev txiav lub peev xwm thiab hnav tsis kam ntawm cov hniav. Qhov siab dua lub hardness, qhov nyuaj rau saum npoo ntawm cov hniav yog kom kos lossis nkag mus, ua rau nws tsim nyog rau kev txiav cov khoom harder.
Yog li, puas muaj qhov txuas tsis tau ntawm Brittleness thiab Hardness? Nyob rau hauv ib txoj kev, nws ua. Cov ntaub ntawv uas nyuaj dua feem ntau muaj cov kev sib tw ua kom muaj zog ntawm cov khoom uas muaj kev cuam tshuam rau sab nraud uas yog qhov txawv txav sab nraud thiab ntau dua yuav ua txhaum. Raws li qhov tshwm sim, cov hlau nyuaj siab yuav muaj ntau nkab zoo li.
Txawm li cas los xij, qhov no tsis txhais tau tias ib hlau nrog cov hlau loj yog qhov tsim nyog. Qhov tseeb, hardness thiab britleness yog ob lub cev sib txawv, thiab tsis muaj kev sib raug zoo ncaj qha ntawm lawv. Hardness feem ntau xav txog cov ntaub ntawv muaj peev xwm tiv thaiv tau raug nias rau hauv lub ntiaj teb sab nraud, thaum kev xav tau ntau dua thaum raug rau sab nraud.
Nyob rau hauvMuaj Hniav Kev Lag Luam, kev xaiv ntawm cov hlau yuav tsum tau ntsuas tiv thaiv hardness thiab britleness nyob ntawm cov xwm txheej tshwj xeeb. Piv txwv li, rau cov hniav uas tau raug rau kev nrawm ib puag ncig thiab kev tawv ntau dua thiab hnav tsis tiv thaiv HSS lossis carbide feem ntau xaiv. Txawm hais tias tus brittle ntawm cov ntaub ntawv no kuj tseem muaj zog, lawv muaj peev xwm tswj cov kev ua tau zoo thiab kev pabcuam lub neej raws cov kev cai tshwj xeeb.
Rau qee qhov tuaj uas yuav tsum tau tiv thaiv kev cuam tshuam loj dua, xws li pom tuaj lossis txiab, koj yuav tsum tau xaiv cov hlau nrog kev nruj dua thiab qis dua brittleness. Qhov no yuav xyuas kom cov hniav tsis yooj yim tawg thaum raug rau sab nraud rog, yog li txuas ntxiv nws lub neej kev pabcuam.
Hauv cov ntsiab lus, kev sib raug zoo ntawm brittleness thiab hardness tsis yog tsuas yog ib feem tsib sib zog sib npaug rau cov hlau hauv kev lag luam hniav kev lag luam. Thaum xaiv cov ntaub ntawv hniav hniav, nws yog ib qho tsim nyog yuav tsum txiav txim siab txog cov yam ntxwv ntawm Hardness, Brittleness, kev ua tiav cov nyhuv txiav zoo tshaj plaws thiab kev pabcuam lub neej.
