Txoj kev loj hlob ntawm aluminium alloy forgings ua raws li cov qauv thoob ntiaj teb
Nyob rau hauv xyoo tas los no, vim lub ntiaj teb sov sov thiab lub zog tsis txaus, aluminium alloy forgings rau tsheb tau tsim sai heev. Lub tsheb lub teeb yuag yog qhov xav tau los txuag lub zog thiab txo cov pa roj carbon dioxide emissions, thiab kev siv ntau ntawm aluminium alloy lub cev thiab qhov chaw tau ua lub luag haujlwm loj hauv kev txo qhov hnyav ntawm lub tsheb.
Niaj hnub no, cov tsheb loj loj xws li Tebchaws Europe, Amelikas thiab Nyij Pooj tau nqis peev ntau ntawm tib neeg thiab cov khoom siv los kawm txog kev hloov cov ntaub ntawv steel nrog aluminium alloy mus rau qhov loj tshaj plaws. Raws li kev txheeb cais, qhov nruab nrab ntawm kev siv aluminium alloy ib lub tsheb hauv Tebchaws Meskas tau mus txog 36.3 feem pua ntawm tag nrho qhov hnyav, thaum qhov nruab nrab siv aluminium alloy ib lub tsheb hauv Tebchaws Europe thiab Nyij Pooj kuj tau tshaj nws tus kheej qhov hnyav los ntawm ntau dua 15 feem pua. Yog li ntawd, qhov kev thov rau aluminium alloy forgings nyob rau hauv kev lag luam manufacturing yog nce explosively. Nyob rau hauv xyoo tas los no, feem ntau ntawm aluminium alloy forgings tsim thoob plaws ntiaj teb tau siv rau tsheb qag, chassis lossis lwm qhov chaw. Nrog rau kev paub txog kev txuag hluav taws xob thiab txo qis qis, aluminium alloy forgings yuav muaj ntau chav rau kev txhim kho.
Malleability tsom xam ntawm wrought aluminium alloy
Malleability yog hais txog lub peev xwm ntawm cov hlau los sau cov pwm zawj nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Nws yog feem ntau siv los ntsuas qhov plasticity thiab deformation tsis kam ntawm cov hlau. Nws yog cov txheej txheem kev ua tau zoo los ntsuas qhov nyuaj ntawm kev tau txais cov khoom zoo los ntawm kev ua cov yas. Qhov siab dua cov yas, qhov me me ntawm qhov deformation tsis kam, qhov zoo dua qhov malleability ntawm cov hlau. Piv nrog cov pa roj carbon steel thiab cov hlau tsis tshua muaj hlau, aluminium alloy muaj zog malleability, uas txiav txim siab tias cov khoom no tsim nyog rau casting thiab forging.
Cov yam ntxwv ntawm kub deformation tsis kam ntawm aluminium alloy
Ua ntej, qhov kub thiab txias deformation tsis kam ntawm ntau yam aluminium alloys sib txawv heev, thiab yuav hloov pauv nrog cov muaj pes tsawg leeg. Qee qhov tsis tshua muaj zog aluminium alloys thiab nruab nrab lub zog aluminium alloys sawv cev los ntawm 6000 series aluminium alloys muaj qhov kub thiab txias deformation tsis kam; Txawm li cas los xij, qee qhov muaj zog aluminium alloys sawv cev los ntawm 7000 series aluminium alloys muaj qhov deformation tsis kam ntawm qhov kub thiab txias. Qee hom aluminium alloy forgings muaj qhov kub thiab txias deformation tsis kam tshaj cov pa roj carbon steel, lwm qhov qis dua carbon steel, los yog roughly sib npaug rau carbon steel, thaum feem ntau cov qauv qis dua carbon steel.
Qhov thib ob, qhov deformation tsis kam ntawm aluminium alloy yog rhiab heev rau qhov kub thiab txias, thiab hloov pauv sai nrog qhov kub thiab txias. Raws li kev txheeb cais, qhov kub thiab txias deformation tsis kam ntawm aluminium alloy nce sai nrog qhov kub thiab txias, thiab qhov kev loj hlob yog siab dua li ntawm cov hlau thiab cov hlau tsis tshua muaj hlau. Thaum qhov kub ntawm cov pa roj carbon steel thiab cov hlau tsis tshua muaj hlau tsis tshua muaj qis dua 100 degree, lub zog txwv nce li 50 feem pua, thaum thaum kub ntawm aluminium alloy txo los ntawm 50 degree, lub zog txwv nce li ntawm 50 feem pua rau 300 feem pua, ntau. siab dua thawj ob.
Yog li ntawd, aluminium alloys, tshwj xeeb tshaj yog cov uas muaj siab alloying degree, tsis raug tso cai los ua qhov kawg forging nyob rau hauv ib tug sov so thiab tsis kub ib puag ncig, uas txwv lub forging kub ntau yam ntawm cov khoom no. Cov neeg ua haujlwm yuav tsum tau ua haujlwm sai sai thaum ua haujlwm kom tsis txhob muaj qhov kub ntawm aluminium alloy siab tshaj qhov tsim nyog. Lub deformation kuj ntawm aluminium alloy nyob rau hauv tuag forging ntau lawm txiav txim lub zog txwv ntawm cov khoom nws tus kheej, ua tej yam kev mob thiab complexity ntawm forgings.
