Lub malleability ntawm iav

Qhov xwm ntawm cov khoom uas tuaj yeem txuas mus rau hauv filaments yam tsis muaj kev tawg raws li kev ua ntawm sab nraud quab yuam hu ua ductility; Cov cuab yeej muaj peev xwm zom tau ib daim ntawv yam tsis tau tawg raws li qhov kev txiav txim ntawm lub zog sab nraud (rauj lossis dov) yog hu ua malleability. Piv txwv li, ductility ntawm hlau yog zoo, uas kub, platinum, tooj liab, nyiaj, tungsten, txhuas yog ductile. Cov ntaub ntawv tsis yog xim hlau xws li quartz thiab iav kuj muaj qee yam ductility ntawm qhov kub thiab txias.
Ductility yog cov cuab yeej ntawm cov khoom siv hlau, thiab ib qho ntawm cov yam ntxwv ntawm cov khoom siv hlau nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam yog tsim cov yas deformation, uas txhais tau hais tias cov ions tuaj yeem txav thiab rov kho dua yam tsis tau poob lub nplaum nplaum, uas yog qhov laj thawj tseem ceeb rau cov ductility. ntawm hlau bonded minerals. Lub ductility ntawm cov hlau sib txawv kuj txawv.
ductility
Lub peev xwm ntawm tus qauv, tus tswv cuab, lossis ntu ntawm tus tswv cuab kom deform nyob rau lub sijhawm los ntawm kev tawm los mus rau qhov muaj peev xwm siab tshaj plaws los yog tom qab ntawd yam tsis muaj qhov txo qis hauv cov kabmob loj. Rau cov qauv nrog zoo ductility, lub lig deformation muaj peev xwm ntawm ib feem los yog ib feem ntawm ib feem yog loj, thiab ib tug npaum li cas ntawm lub zog tseem yuav absorbed tom qab mus txog lub xeev ntawm yield los yog siab tshaj bearing peev xwm, thiab qhov tshwm sim ntawm brittle tsis ua hauj lwm muaj peev xwm. zam dhau.
Ductility yog lub cev muaj zog. Nws yog hais txog cov yas deformation muaj peev xwm ntawm cov khoom ua ntej nws raug yuam kom tsim kev puas tsuaj, thiab muaj feem xyuam rau cov ductility ntawm cov khoom. Piv txwv li, kub, tooj liab, txhuas, thiab lwm yam yog cov ntaub ntawv uas muaj ductility siab. Platinum yog cov hlau zoo tshaj plaws.
brittle tsis ua hauj lwm (kev tsis ua hauj lwm brittle) Ib tug qauv los yog cov khoom tsis muaj qhov tseem ceeb deformation los yog lwm yam kev twv ua ntej tsis ua hauj lwm. ductile tsis ua hauj lwm Ib hom tsis ua hauj lwm nyob rau hauv uas ib tug qauv los yog cov khoom yog pom deformed los yog lwm yam preconceived ua ntej tsis ua hauj lwm.
Nyob rau hauv kev cuam tshuam thiab kev vibration load, cov khoom ntawm cov qauv yuav tsum tau nqus ib tug loj npaum li cas ntawm lub zog, thiab nyob rau tib lub sij hawm, nws muaj peev xwm tsim ib tug tej yam deformation yam tsis muaj kev puas tsuaj, uas yog, cov qauv los yog cov tswv cuab yuav tsum tau muaj zoo ductility. . Piv txwv li, steel qauv cov ntaub ntawv muaj ductility zoo thiab muaj peev xwm tiv taus av qeeg tsis muaj zog; Txawm li cas los xij, cov qauv masonry muaj peev xwm deformation tsis zoo thiab muaj qhov ua rau tsis ua haujlwm thiab tawg hauv av qeeg muaj zog. Vim li no, masonry qauv tsev yuav tsum tau teeb tsa cov qauv kab thiab seismic nplhaib beams raws li seismic code yuav tsum tau, txwv tsis pub deformation ntawm masonry, thiaj li yuav ua rau kom nws muaj peev xwm tiv thaiv kev sib tsoo nyob rau hauv av qeeg. Reinforced qhob cov khoom muaj ob qhov xwm txheej, yog tias tsim nyog, tuaj yeem tshem tawm lossis txo qhov kev puas tsuaj ntawm cov khoom vaj khoom tsev, muab kev ua si tag nrho rau cov cuab yeej yas ntawm steel tuav, kom ua tiav cov qauv ductile. Yog li ntawd, cov av qeeg-resistant reinforced pob zeb yuav tsum tau tsim raws li cov kev cai ntawm ductility qauv kom ua tiav peb theem ntawm av qeeg-resistant fortification: cov qauv yog nyob rau hauv elastic xeev nyob rau hauv me me av qeeg; Thaum muaj av qeeg nruab nrab, cov qauv yuav raug puas tsuaj, tab sis nws tuaj yeem siv txuas ntxiv tom qab kho; Thaum muaj av qeeg loj, cov qauv yuav raug puas tsuaj me ntsis, tab sis nws yuav tsis tawg lossis ua rau muaj kev phom sij rau lub neej.
