Nyob rau hauv cov qauv steel yeeb nkab, tensile zog, hardness thiab toughness ntsuas tau teev raws li kev siv sib txawv, nrog rau cov khoom kub thiab kub uas cov neeg siv.
tensile zog. Thaum lub sij hawm stretching txheej txheem, lub zog loj dhau los ntawm tus qauv thaum nws tawg tau muab faib los ntawm qhov qub ntu ntu ntawm cov qauv, thiab qhov kev ntxhov siab tshwm sim yog hu ua tensile zog. Nws sawv cev rau qhov muaj peev xwm ntau dua ntawm cov khoom siv hlau los tiv thaiv kev puas tsuaj hauv qhov nro.
Yield point. Rau cov khoom siv hlau uas muaj qhov tshwm sim tshwm sim, qhov kev ntxhov siab uas cov qauv tuaj yeem txuas ntxiv mus ntxiv yam tsis muaj zog ntxiv thaum lub sijhawm ncab yog hu ua qhov taw tes tawm. Yog tias lub zog txo qis, cov ntsiab lus sab saud thiab qis dua yuav tsum tau paub qhov txawv.
Elongation tom qab so. Hauv kev sim tensile, qhov feem pua ntawm qhov ntev ntawm qhov ntsuas qhov ntev ntawm cov qauv tom qab nws tawg mus rau qhov ntsuas qhov ntev yog hu ua elongation.
tus nqi txo hauv cheeb tsam. Hauv kev sim tensile, qhov sib piv ntawm qhov txo qis tshaj plaws hauv cheeb tsam cross-sectional ntawm qhov txo txoj kab uas hla tom qab cov qauv raug tawg mus rau qhov qub ntu ntu yog hu ua cheeb tsam shrinkage.
Hardness index. Lub peev xwm ntawm cov khoom siv hlau los tiv thaiv qhov indentation ntawm qhov chaw los ntawm cov khoom tawv yog hu ua hardness. Raws li cov kev sim sib txawv thiab daim ntawv thov, qhov nyuaj tuaj yeem muab faib ua Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness thiab kub hardness.
