1.Dab tsi yog qhov cuam tshuam ntawm cov kev hloov pauv hauv cov strain hardening index?
Lub peev xwm ntawm cov khoom siv los tiv thaiv ib puag ncig thinning thiab zoo ib yam deformation thaum stretching.
Qhov loj n tus nqi qhia tau hais tias muaj zog ua hauj lwm hardening, ntau uniform deformation faib, thiab muaj zog tensile tawg kuj.
2.Dab tsi yog qhov cuam tshuam ntawm kev hloov pauv ntawm cov yas strain piv?
Qhov ratio ntawm strain nyob rau hauv dav kev taw qhia mus rau strain nyob rau hauv lub thickness kev taw qhia ntsuas qhov tsis kam mus rau thinning.,
Qhov loj dua r- tus nqi qhia tau hais tias muaj teeb meem ntau dua hauv kev ua kom cov tuab tuab thiab muaj zog tiv thaiv tensile cracking thiab wrinkling ntawm phab ntsa.
3.Koj yuav ua li cas yog tias koj xav tias ib pawg ntawm cov ntaub ntawv "tsis ua haujlwm zoo"?
Ua cov kev xeem cupping ntawm cov khoom uas xav tias muaj teeb meem thiab paub 合格 (tsim nyog) batches nyob rau hauv tib yam.
Qhov sib txawv ntawm IE (Intrudement) tus nqi> 1.0 mm yog txaus los txiav txim siab qhov sib txawv ntawm cov khoom siv.
Cov txheej txheem tseem ceeb: Cov khoom siv nrog tus nqi IE < 9.0 mm feem ntau tsis muaj peev xwm kos duab sib sib zog nqus.
4.Dab tsi yog qhov cuam tshuam ntawm kev hloov pauv hauv anisotropy ntawm lub dav hlau?
Qhov℃ntawm qhov sib txawv ntawm r qhov tseem ceeb hauv cov lus qhia sib txawv
Qhov ze dua Δr yog rau 0, qhov me me ntawm anisotropy, thiab tsawg dua pob ntseg (bulging) tom qab stamping.
5.Yuav ua li cas sai sai ua rau kev sib piv rau sab hauv kev sim cupping?
Ua cov kev xeem cupping ntawm cov khoom uas xav tias muaj teeb meem thiab paub 合格 (tsim nyog) batches nyob rau hauv tib yam.
Qhov sib txawv ntawm IE (Intrudement) tus nqi> 1.0 mm yog txaus los txiav txim siab qhov sib txawv ntawm cov khoom siv.
Cov txheej txheem tseem ceeb: Cov khoom siv nrog tus nqi IE < 9.0 mm feem ntau tsis muaj peev xwm kos duab sib sib zog nqus.
