Kev piav qhia: Raws li tus nqi thauj khoom (tus nqi lim) nce, qhov tawv ntawm cov khoom txo qis. Nrog nce kub ductility thiab toughness nce. Alloying thiab grain refinement kuj txhim kho toughness ntawm cov khoom.
Dab tsi yog yam cuam tshuam rau qhov toughness ntawm cov hlau?
Toughness yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj. Cov yam ntxwv dav dav, cuam tshuam rau qhov toughness ntawm cov khoom yog: kub, strain rate, kev sib raug zoo ntawm lub zog thiab ductility ntawm cov khoom thiab muaj kev ntxhov siab concentration (notch) ntawm tus qauv nto
Yuav ua li cas thiaj ua tau siab tawv?
Tus yuam sij rau qhov tawv yog qhov zoo ua ke ntawm lub zog thiab ductility. Cov khoom siv nrog lub zog siab thiab siab ductility yuav muaj zog ntau dua li cov khoom siv uas tsis muaj zog thiab siab ductility.
Qhov cuam tshuam ntawm qhov kub ntawm qhov toughness yog dab tsi?
Nws tuaj yeem pom tias thaum qhov kub tsis tshua muaj qhov khoom yog nkig ntau thiab cuam tshuam toughness tsawg. Ntawm qhov kub thiab txias, cov khoom siv ntau dua thiab qhov cuam tshuam toughness siab dua.
Yam khoom twg tawv dua?
Txawm hais tias diamonds feem ntau hu ua cov khoom siv nyuaj tshaj plaws hauv ntiaj teb, muaj rau 6 cov khoom uas nyuaj dua. Pob zeb diamond tseem yog ib qho nyuaj tshaj plaws uas tshwm sim thiab muaj ntau cov ntaub ntawv nyob rau hauv lub ntiaj teb, tab sis rau cov ntaub ntawv no tag nrho nws yeej.
