pob zeb diamond. Unmatched nyob rau hauv nws lub peev xwm los tiv thaiv raug khawb, lub gemstone no nyiam heev nyob rau hauv lub siab tshaj plaws nyob rau hauv cov nqe lus ntawm hardness. Pob zeb diamond yog ib txwm tshwm sim ceramic ua los ntawm cov pa roj carbon atoms ruaj khov ua ke nyob rau hauv ib lub lattice.
Cov khoom twg muaj zog thiab tawv?
Maraging steel Nws yog ib qho hlau-ib qho sib xyaw ntawm cov hlau-uas yog siv los kho cua sov, txheej txheem uas ua rau nws nyuaj thiab tawv heev. Maraging steel kuj muaj peev xwm tiv taus lub zog rub, lossis nro (lub zog tensile). Nws tuaj yeem nqus tau ntau lub zog ua ntej nws deforms.
Dab tsi yog cov khoom toughness?
Toughness yog cov khoom siv tseem ceeb ntsuas lub peev xwm ntawm cov khoom siv los nqus lub zog thiab tiv thaiv kev poob siab txog kev tawg; uas yog, muaj peev xwm nqus tau lub zog hauv cov khoom yas.… Cov ntaub ntawv tawv tuaj yeem nqus tau ntau lub zog ua ntej tawg, thaum cov khoom nkig nqus tau tsawg heev.
Yuav ua li cas yog cov piv txwv ntawm toughness?
Toughness muaj feem cuam tshuam rau thaj tsam hauv qab kev ntxhov siab-txoj kab nkhaus. Txhawm rau ua kom tawv, cov khoom siv yuav tsum muaj zog thiab du. Piv txwv li, cov ntaub ntawv nkig (xws li ceramics)uas muaj zog tab sis muaj qhov txwv tsis pub muaj qhov tsis zoo; conversely, cov ntaub ntawv ductile heev nrog tsawg zog kuj tsis tawv.
Puas steel muaj toughness?
Strength: Tus nqi ntawm lub zog tsim nyog rau cov khoom siv kom deform. Qhov siab dua lub zog yuav tsum tau hloov cov duab ntawm cov khoom, cov khoom muaj zog dua. Hlau tsis yooj yim rau rub tawm, yog li nws muaj lub zog siab…
