JFE 50JN250 Mechanical
Qhov taw tes tawm los yog qhov taw tes tawm ntawm JFE 50JN250 thaum yielding tshwm sim, uas yog, kev ntxhov siab uas tiv thaiv microplastic deformation. Kev quab yuam sab nraud ntau dua li lub zog tawm los yuav ua rau JFE 50JN250 qhov chaw ua tsis tiav thiab tsis tuaj yeem rov qab tau. Yog tias nws tsawg dua, JFE 50JN250 qhov chaw yuav rov qab mus rau lawv cov qauv qub.
Lub zog tensile yog qhov tseem ceeb ntawm kev hloov pauv ntawm cov yas deformation mus rau hauv zos concentrated yas deformation. Nws tseem yog lub siab tshaj plaws load peev xwm ntawm JFE 50JN250 nyob rau hauv static nro. Lub zog tensile yog lub zog uas qhia txog qhov siab tshaj plaws ntawm cov yas deformation ntawm JFE 50JN250. Lub deformation ntawm lub tensile specimens yog ib yam ua ntej lawv txhawb lub siab tshaj plaws tensile kev nyuaj siab, tab sis tshaj li ntawd, lub JFE 50JN250 pib dai, uas yog, mloog mus rau lub deformation.
