1. Performance index tsom xam tshwj xeeb-zoo li tus steel yeeb nkab - plasticity
Plasticity yog hais txog lub peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
2. Performance index tsom xam tshwj xeeb-zoo li tus steel yeeb nkab - hardness
Hardness yog lub pointer los ntsuas qhov hardness ntawm cov ntaub ntawv hlau.Txoj kev siv ntau tshaj plaws rau kev ntsuas hardness hauv kev tsim khoom yog txoj kev indentation hardness, uas yog siv lub indenter nrog ib qho geometry los nias rau hauv qhov chaw ntawm cov khoom siv hlau kuaj nyob rau hauv ib qho kev thauj khoom, thiab txiav txim siab nws cov nqi hardness raws li qib. ntawm indentation.
Cov kev siv feem ntau suav nrog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV).
3. Performance index tsom xam tshwj xeeb-zoo li tus steel yeeb nkab - qaug zog
Lub zog, plasticity thiab hardness tau tham saum toj no yog tag nrho cov kev ntsuas ntawm cov khoom siv hluav taws xob ntawm cov hlau hauv qab cov khoom zoo li qub.Qhov tseeb, ntau lub tshuab qhov chaw ua haujlwm nyob rau hauv cyclic load, thiab nyob rau hauv cov xwm txheej no, qaug zog yuav tshwm sim.
4. Performance index tsom xam tshwj xeeb-zoo li tus steel yeeb nkab - cuam tshuam toughness
Lub load ua haujlwm ntawm lub tshuab ntawm qhov nrawm yog hu ua cuam tshuam load, thiab lub peev xwm ntawm cov hlau los tiv thaiv kev puas tsuaj nyob rau hauv kev cuam tshuam load yog hu ua cuam tshuam toughness.
5. Performance index tsom xam tshwj xeeb-zoo li tus steel yeeb nkab - lub zog
Lub zog yog hais txog qhov tsis kam ntawm cov ntaub ntawv hlau rau kev ua tsis tiav (cov yas deformation ntau dhau los yog tawg) nyob rau hauv cov khoom zoo li qub.Txij li cov kev ua haujlwm ntawm cov khoom muaj xws li nro, compression, dabtsi yog khoov thiab shear, lub zog kuj muab faib ua tensile zog, compressive zog, khoov lub zog thiab shear zog.Feem ntau muaj qee qhov kev sib txuas ntawm ntau lub zog.Feem ntau, lub zog tensile yog qhov taw qhia lub zog tshaj plaws hauv kev siv.
