Yam cuam tshuam rau qhov zoo ntawm cov hlau stamped qhov chaw.

(1) Tshuaj muaj pes tsawg leeg ntawm cov hlau
Cov hlau ntshiab muaj ductility zoo dua li cov alloys. Cov ntsiab lus impurity feem ntau ua rau brittleness thiab txo ductility. Cov alloys sib txawv muaj qhov sib txawv ntawm qhov ductility.
(2) Hlau qauv
Cov qauv ib-theem muaj ntau dua ductility ntau dua li cov qauv multiphase Cov xwm txheej, cov duab, qhov loj, qhov ntau thiab kev faib tawm ntawm theem ob yog qhov sib txawv, thiab lawv cov nyhuv ntawm ductility kuj txawv. Cov qauv zoo-grained muaj ductility zoo dua. tshaj ib coarse-grained qauv Casting cov qauv muaj cov loj columnar nplej thiab tsis xws luag nyob rau hauv daim ntawv ntawm segregation, inclusions, npuas, porosity, uas txo cov ductility ntawm cov hlau.
(3) Deformation kub
Raws li qhov kub nce thaum lub sij hawm stamping txheej txheem, ductility kuj nce, tab sis qhov nce tsis yog ib qho yooj yim linear nce.
(4) Tus nqi zog
Ib qho kev nce ntawm cov strain tsis tsuas yog txo cov ductility ntawm cov hlau, tab sis kuj ua rau kom cov ductility ntawm cov hlau ua ke ua ke ntawm ob yam no thaum kawg txiav txim siab qhov hloov ntawm cov ductility ntawm cov hlau. Cov nyhuv ntawm strain tus nqi ntawm cov ductility ntawm cov hlau thaum lub sij hawm kub deformation yog ntau dua thaum lub sij hawm txias deformation ntawm txawv deformation kub, cov nyhuv ntawm strain rate ntawm ductility kuj txawv.
(5) Mechanical deformation tej yam kev mob
Qhov ntau dua qhov compressive stresses thiab qhov ntau dua tus nqi ntawm lub ntsiab kev ntxhov siab, qhov zoo dua qhov ductility ntawm cov hlau. Ntawm qhov tsis sib xws, yog tias tus naj npawb ntawm tensile stresses ntau dua thiab qhov loj dua, ces qhov ductility ntawm cov hlau yuav phem dua. Compressive deformation txhawb txoj kev loj hlob ntawm plasticity, thiab tensile deformation yog detrimental rau plasticity Qhov zoo tshaj plaws rau txoj kev loj hlob yog txoj kev plasticity nrog peb-sided daim duab ntawm lub ntsiab compression stresses thiab ib daim duab ntawm lub ntsiab deformations ntawm ob txoj kev compression thiab ib qho. - txoj kev nro. plasticity ntawm hlau.
(6) Lwm yam
Nrog kev sib cuam tshuam deformation, ductility ntawm cov hlau kuj tuaj yeem txhim kho, tshwj xeeb tshaj yog thaum thermal deformation ntawm cov hlau tsis tshua muaj plasticity. Qhov loj dua qhov loj ntawm lub cev deformation, qhov qis dua cov yas, txawm li cas los xij, thaum qhov loj ntawm lub cev deformation ncav cuag ib qho tseem ceeb ntawm cov khoom, cov yas yuav tsis txo nrog qhov ntim ntau ntxiv.
