Monga mukudziwa.athuzitsulo za aluminiyamu/ aluminium skirting / mbiri ya aluminiyamu yotsogolera / mbiri yokongoletsera ya aluminiyumu imapangidwa ndi 6063 aluminium alloy.chinthu cha aluminiyamu ndicho gawo lalikulu.ndipo zina zonse zidzakhala monga pansipa.
Ndipo lero tifotokoza ntchito ndi mphamvu ya zinthu zosiyanasiyana mu zitsulo zotayidwa pa katundu wa aluminiyamu zipangizo.
mkuwa element
Pamene zotayidwa wolemera mbali ya zotayidwa-mkuwa aloyi ndi 548, pazipita solubility mkuwa zotayidwa ndi 5.65%, ndipo pamene kutentha akutsikira 302, solubility mkuwa ndi 0,45%.Mkuwa ndi chinthu chofunika kwambiri cha alloying ndipo chimakhala ndi njira yolimba yolimbikitsa.Kuphatikiza apo, CuAl2 yoyambitsidwa ndi ukalamba imakhala ndi mphamvu yolimbitsa ukalamba.Zomwe zili mkuwa muzitsulo za aluminiyumu nthawi zambiri zimakhala 2.5% mpaka 5%, ndipo mphamvu yolimbikitsa imakhala yabwino kwambiri pamene mkuwa uli ndi 4% mpaka 6.8%, kotero kuti mkuwa wazitsulo zolimba kwambiri za aluminiyumu zimakhala mumtundu uwu.
Silicon element
Pamene gawo lolemera kwambiri la aluminium la Al-Si alloy system lili pa kutentha kwa eutectic 577 ° C, kusungunuka kwa silicon mu njira yolimba ndi 1.65%.Ngakhale kusungunuka kumachepa ndi kutentha kochepa, ma aloyiwa nthawi zambiri satha kuchiritsidwa ndi kutentha.Ma alloys a Al-Si ali ndi kuthekera kwakukulu komanso kukana dzimbiri.
Ngati magnesium ndi silicon zikuwonjezedwa ku aluminiyumu nthawi yomweyo kupanga aluminium-magnesium-silicon alloy, gawo lolimbikitsa ndi MgSi.Kuchuluka kwa magnesium ku silicon ndi 1.73: 1.Popanga mapangidwe a aloyi ya Al-Mg-Si, zomwe zili mu magnesium ndi silicon ziyenera kukhazikitsidwa molingana ndi chiŵerengero ichi pa gawo lapansi.Ma aloyi ena a Al-Mg-Si, kuti apititse patsogolo mphamvu, amawonjezera mkuwa woyenerera, ndipo nthawi yomweyo onjezani chromium yoyenerera kuti athetse vuto la mkuwa pakukana dzimbiri.
Al-Mg2Si alloy alloy equilibrium gawo chithunzi Kusungunuka kwakukulu kwa Mg2Si mu aluminiyamu mu gawo lolemera kwambiri la aluminiyamu ndi 1.85%, ndipo kuchepa kwake kumakhala kochepa ndi kuchepa kwa kutentha.
M'magulu opunduka a aluminiyumu, kuwonjezera kwa silicon ku aluminiyamu kokha kumangokhala ndi zida zowotcherera, ndipo kuwonjezera kwa silicon ku aluminiyumu kumakhalanso ndi mphamvu yolimbitsa.
Magnesium element
Gawo lolemera kwambiri la aluminiyamu la gawo lofananira la dongosolo la Al-Mg aloyi, ngakhale pamapindikira osungunuka akuwonetsa kuti kusungunuka kwa magnesium mu aluminiyamu kumachepa kwambiri ndi kuchepa kwa kutentha, koma m'mafakitale ambiri opunduka aloyi zotayidwa, zomwe zili mu magnesium. ndi zosakwana 6%.Zomwe zili mu silicon ndizochepa.Mtundu woterewu wa alloy sungalimbitsidwa ndi chithandizo cha kutentha, koma umakhala ndi weldability wabwino, kukana kwa dzimbiri, komanso mphamvu yapakatikati.
Kulimbitsa kwa magnesium kupita ku aluminiyamu kumawonekera.Pachiwonjezeko chilichonse cha 1% cha magnesium, mphamvu yamanjenje imakwera pafupifupi 34MPa.Ngati manganese awonjezedwa pansi pa 1%, amatha kuwonjezera kulimbikitsa.Choncho, mutatha kuwonjezera manganese, magnesiamu amatha kuchepetsedwa, ndipo panthawi imodzimodziyo, chizolowezi chowotcha chikhoza kuchepetsedwa.Kuphatikiza apo, manganese amathanso kupangitsa kuti Mg5Al8 pawiri ikhale yolimba, ndikuwongolera kukana kwa dzimbiri ndi kuwotcherera.
Manganese
Kusungunuka kwakukulu kwa manganese mu njira yolimba ndi 1.82% pamene kutentha kwa eutectic ndi 658 mu chithunzi chofanana cha Al-Mn alloy system.Mphamvu ya aloyi imawonjezeka mosalekeza ndi kuwonjezeka kwa kusungunuka, ndipo elongation imafika pamtunda pamene manganese ali ndi 0,8%.Al-Mn alloys ndi osakalamba owumitsa alloys, ndiye kuti, sangathe kulimbikitsidwa ndi kutentha kutentha.
Manganese angalepheretse recrystallization ndondomeko aloyi zotayidwa, kuonjezera kutentha recrystallization, ndipo akhoza kwambiri kuyenga mbewu recrystallization.Kukonzanso kwa njere zowumbidwanso kumachitika makamaka chifukwa cholepheretsa kukula kwa njere zowonjezeredwa kudzera mu tinthu tambiri ta MnAl6.Ntchito ina ya MnAl6 ndikusungunula chitsulo chodetsedwa kupanga (Fe, Mn) Al6, kuchepetsa zotsatira zovulaza zachitsulo.
Manganese ndi gawo lofunikira la ma aloyi a aluminiyamu, omwe amatha kuwonjezeredwa okha kuti apange ma aloyi a Binary Al-Mn, ndipo nthawi zambiri amawonjezeredwa pamodzi ndi zinthu zina, kotero ma aloyi ambiri a aluminiyumu amakhala ndi manganese.
Zinc element
Kusungunuka kwa zinki mu aluminiyamu ndi 31.6% pamene gawo lolemera kwambiri la aluminiyumu la Al-Zn alloy system equilibrium phase diagram ndi 275, ndipo kusungunuka kwake kumatsika mpaka 5.6% pamene ndi 125.
Zinc ikawonjezeredwa ku aluminiyamu yokha, kuwongolera kwa mphamvu ya aloyi ya aluminiyamu pansi pamikhalidwe yopunduka kumakhala kochepa kwambiri, komanso pali chizolowezi chokakamiza kusweka kwa dzimbiri, komwe kumachepetsa kugwiritsa ntchito kwake.
Zinc ndi magnesium zimawonjezeredwa ku aluminiyumu nthawi yomweyo kuti apange gawo lolimbikitsa Mg / Zn2, lomwe limalimbitsa kwambiri alloy.Pamene zinthu za Mg / Zn2 zikuwonjezeka kuchokera ku 0.5% mpaka 12%, mphamvu zowonongeka ndi zokolola zimatha kuwonjezeka kwambiri.Zomwe zili mu magnesium zimaposa zomwe zimafunikira kuti pakhale gawo la Mg/Zn2.Mu ma aluminiyamu olimba kwambiri, pamene chiŵerengero cha zinki ndi magnesiamu chimayang'aniridwa pafupifupi 2.7, kukana kwa corrosion corrosion ndikokukulirakulira.
Ngati mkuwa wawonjezedwa ku Al-Zn-Mg kuti apange Al-Zn-Mg-Cu aloyi, mphamvu yolimbitsa matrix ndi yayikulu kwambiri pakati pa ma aluminiyamu onse, komanso ndi chinthu chofunikira kwambiri cha aluminiyamu muzamlengalenga, makampani oyendetsa ndege, ndi magetsi. makampani opanga magetsi.
