Cov cuab yeej ua haujlwm ntawm cov hlau feem ntau yog cov hauv qab no:
Lub zog tensile: qhov no yog qhov ntau tshaj plaws kev ntxhov siab uas cov hlau tuaj yeem tiv thaiv ua ntej tawg, thiab yog qhov tseem ceeb ntsuas ntsuas qhov muaj peev xwm tiv thaiv tensile puas. Qhov siab dua lub tensile lub zog, muaj zog rau cov kabmob muaj peev xwm ntawm cov hlau.
Tos lub zog: Hais txog qhov kev ntxhov siab tus nqi ntawm cov hlau uas pib tsim cov khoom muaj kuab yooj yim dua thaum raug kom nruj. Qeb ntawm cov txiaj ntsig lub zog xav txog qhov muaj peev xwm ntawm cov hlau los tuav cov qauv txheej txheem kev ua kom ncaj ncees tom qab coj qee yam.
Kev Tshawb Fawb: Qhov taw qhia tseem ceeb los ntsuas cov yas ua kom muaj peev xwm ntawm cov hlau, uas qhia tau qhov feem pua ntawm cov hnoos qeev ntawm qhov ntev. Qhov siab dua elongation, qhov zoo dua yas thiab ductility ntawm cov hlau, uas tuaj yeem nqus tau zoo dua qub thiab tiv thaiv tus qauv los ntawm kev rhuav tshem lub sij hawm lossis overload.
Kev Cuam Tshuam Cov tawv: Hais txog qhov muaj peev xwm ntawm cov hlau kom tiv thaiv pob txha tawg hauv qab cov khoom siv. Qhov ntau dua qhov kev cuam tshuam nyuaj, tsawg kawg cov hlau yog tawg thaum muaj kev cuam tshuam rau cov txheej txheem uas yuav tsum tau tiv thaiv cov khoom cuam tshuam.
Hardness: Muaj peev xwm tiv thaiv cov khoom tsis zoo, los ntawm cov khoom sab nraud nias rau hauv cov nplaim hluav taws xob hauv zos. Hardness yog qhov taw qhia tseem ceeb rau kev ntsuas cov hnav tsis kam thiab cov hlau.
Qoob qaug zog: nyob rau hauv cov load tsis zoo, cov tshwm sim uas steel dheev tawg thaum nws nyob deb hauv tensile muaj zog yog hu ua kev qaug zog. Lub qaug zog tsis muaj kev ntxhov siab tshaj plaws uas cov quav me me ua haujlwm tsis muaj kev ntxhov siab thiab tsis ua txhaum nyob rau hauv lub hauv paus teev tseg.
Txias dabtsi puas yog lawm kev ua tau zoo: yog hais txog lub peev xwm ntawm cov hlau kom walland demist deformation ntawm chav tsev kub. Tsim Nyog Qhov Kev Ua Si Txias Dab Tsi Qhia tau qhia tias cov yas ua tau zoo ntawm cov hlau ua tau thiab haum rau cov qauv uas yuav tsum tau ua haujlwm txias zoo.
Vuam kev ua haujlwm: yog hais txog kev ua yeeb yam ntawm cov hlau thaum lub sij hawm vuam, suav nrog qib kev sib xws ntawm cov khoom ntawm Weld thiab cov khoom siv ntawm niam txiv. Kev siv vuam zoo ua kom ntseeg tau tias cov qauv tseem tuaj yeem tswj cov khoom siv muaj kev ruaj khov tom qab vuam.
Cov ntsuas kev ua haujlwm no ua ke ua ke txiav txim siab kev nyab xeeb thiab kav siv hlau ntawm cov tshuab engineering. Nkag siab cov kev ua tau zoo no yog qhov tseem ceeb rau cov engineers, cov neeg tsim qauv, thiab cov kws tshawb fawb thaum xaiv thiab siv hlau.
