Lub thickness ntawm LR AH32 Steel Phaj muaj qhov cuam tshuam loj rau nws cov khoom siv kho tshuab, raws li cov lus qhia hauv qab no:

Yield zog

 

Feem ntau, qhov tsawg kawg nkaus tawm lub zog rau LR AH32 steel phaj yog ntau dua los yog sib npaug rau 315 MPa tsis hais qhov tuab ntawm cov khoom siv feem ntau. Txawm li cas los xij, hauv kev xyaum, cov phaj tuab tuaj yeem muaj qhov qis dua qhov tseeb ntawm lub zog piv rau cov thinner. Qhov no yog vim tias qhov txias txias thaum lub sijhawm tsim khoom qeeb qeeb rau cov ntu tuab, uas tuaj yeem ua rau coarser grain qauv. Coarser nplej tuaj yeem txo cov khoom tsis kam rau cov yas deformation rau qee qhov, ua rau lub zog tawm los ze zog rau qhov tsawg kawg nkaus tus nqi lossis txawm tias me ntsis hauv qab nws hauv qee kis. Piv txwv li, 5 hli tuab LR AH32 phaj yuav muaj lub zog tawm los ze zog rau qhov kawg ntawm qhov kev tso cai nyob rau hauv ib txwm tsim khoom, thaum lub phaj tuab 50 hli tuaj yeem muaj lub zog tawm los ze rau qhov tsawg kawg nkaus.

 

Tensile zog

 

Lub zog tensile ntawm LR AH32 steel phaj yog teev nyob rau hauv qhov ntau ntawm 440 - 570 MPa. Cov phaj tuab yuav muaj lub zog tensile qis dua nyob rau hauv qhov no piv rau cov thinner. Yog vim li cas zoo ib yam li ntawd rau yield zog; Qhov qeeb qeeb qeeb hauv cov phaj tuab ua rau cov nplej loj dua thiab cov yam ntxwv sib txawv ntawm microstructural. Cov yam ntxwv no tuaj yeem cuam tshuam rau cov khoom muaj peev xwm tiv taus lub zog tensile thiab ua rau lub zog tensile qis dua. Piv txwv li, thaum kuaj cov qauv ntawm cov thicknesses sib txawv, 10 hli tuab phaj tuaj yeem pom lub zog tensile ze rau 570 MPa, thaum lub phaj tuab 100 hli tuaj yeem qhia lub zog tensile ze rau 440 MPa.

Elongation

 

Elongation yog ib qho tseem ceeb qhia txog cov hlau ductility. Raws li lub thickness ntawm LR AH32 steel phaj nce, qhov feem pua ​​elongation feem ntau txo. Thicker daim hlau muaj ntau inhomogeneities nyob rau hauv thiab loj grain qauv vim cov txheej txheem tsim, uas txwv tsis pub cov khoom muaj peev xwm deform uniformly nyob rau hauv tensile kev nyuaj siab. Yog li ntawd, lawv tsis tshua muaj peev xwm ncab thiab qhia qis elongation qhov tseem ceeb. Piv txwv li, nyias LR AH32 phaj nrog lub thickness ntawm ib ncig ntawm 6 hli yuav muaj ib tug elongation feem pua ​​ze rau lub sab sauv txwv ntawm tus qauv yuav tsum tau, hais ib ncig ntawm 25%, thaum lub phaj tuab nrog ib tug tuab ntawm 80 hli yuav muaj ib tug elongation feem pua. ze rau qhov tsawg kawg nkaus tus nqi, tej zaum nyob ib ncig ntawm 22%.

 

Impact Toughness

 

Impact toughness yog qhov tseem ceeb heev rau kev tiv thaiv tam sim ntawd dynamic loads. Thicker LR AH32 steel phaj feem ntau muaj qhov cuam tshuam qis dua piv rau cov thinner. Qhov qis qis qis hauv cov ntu tuab ua rau coarser grain qauv thiab muaj peev xwm tsim cov microstructural defects. Cov yam ntxwv no ua rau cov hlau ua rau cov pob txha tawg yooj yim dua thaum raug cuam tshuam rau cov quab yuam, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias. Piv txwv li, ntawm 0 degree , ib lub phaj nyias nyias tuaj yeem nqus tau ntau qhov cuam tshuam lub zog, yooj yim sib ntsib lossis tshaj qhov kev xav tau ntawm lub zog tsawg kawg nkaus. Hauv qhov sib piv, lub phaj tuab yuav tawm tsam kom ncav cuag qhov tsawg kawg nkaus uas yuav tsum muaj kev cuam tshuam rau lub zog thiab tuaj yeem ua rau muaj kev pheej hmoo siab dua ntawm nkig tsis ua haujlwm nyob rau hauv tib qho kev cuam tshuam.
