Rau cov hlau pearlitic tag nrho, raws li qhov sib txawv interlamellar ua finer, lub zog, toughness thiab ductility tag nrho nce. Yog li ntawd, nyob rau hauv kev sib raug zoo ntawm cov khoom vaj khoom tsev nws yog ib qho tseem ceeb los ntsuas qhov sib txawv interlamellar. Daim ntawv no tshuaj xyuas cov txheej txheem rau kev ntsuas qhov ntsuas.
Dab tsi yog interlamellar spacing?
INTERLAMELLAR SPACING. Ib qho kev ntsuas ntawm fineness ntawm lub lamellar qauv yog qhov. qhov tseeb interlamellar qhov sib nrug, A0, txhais tau tias yog lub perpendicular . distance hla ob lamellae sib law liag, piv txwv li, ferrite thiab. cementite.
Lub zog ntawm pearlite cuam tshuam li cas?
Qhov cuam tshuam lub zog nce ntxiv nrog cov ntsiab lus pearlitehauv cov welds Fig. [8] thiab cov nplej loj ntawm cov ntsiab lus ferrite.
Yuav ua li cas cov cementite lamellae hauv pearlite nce lub zog ntawm cov hlau?
Tus nqi ntawm pearlite hauv cov qauv nce nrog cov ntsiab lus carbon ntxiv. Lub zog ntawm cov hlau nce nrog cov nyiaj pearlite thiab lub zog ntawm pearlite tuaj yeem nce ntxiv los ntawm txo qhov sib nrug ntawm cov ntawv hloov pauv ntawm ferrite thiab cementite.
Dab tsi yog daws pearlite?
Nyob rau hauv steel hlau rods nrog cov ntsiab lus carbon ntau dua li cov eutectoid muaj pes tsawg leeg, proeutectoid cementite cov ntaub ntawv raws li cov ciam teb ua ntejmus rau tsim pearlite thaum kub dov.
