Mapangidwe ndi Alloying Elements
The5-mndandanda wa aluminiyamu aloyi mbale, omwe amadziwikanso kuti aluminium-magnesium alloys, ali ndi magnesium (Mg) monga gawo lawo lalikulu la alloying. Zomwe zili ndi magnesium nthawi zambiri zimachokera ku 0.5% mpaka 5%. Kuphatikiza apo, zinthu zina zazing'ono monga manganese (Mn), chromium (Cr), ndi titaniyamu (Ti) zitha kuwonjezeredwa. Manganese amathandizira kulimbitsa mphamvu komanso kukana dzimbiri, pomwe chromium imatha kupititsa patsogolo magwiridwe antchito komanso kukhazikika kwa aloyi panthawi yamankhwala otentha. Titaniyamu imawonjezedwa pang'onopang'ono kuti iyeretsenso kapangidwe kambewu, potero kumapangitsa kuti makina onse aziwoneka bwino.
Mechanical Properties
Mphamvu
Ma alloy mbale awa amakwaniritsa bwino pakati pa mphamvu ndi mawonekedwe. Mphamvu zokolola za 5-series alloys zimatha kuchokera ku 100 megapascals kupita ku 300 megapascals, kutengera mtundu wa aloyi ndi kupsya mtima kwake. Mwachitsanzo, aloyi 5083 mu H321 kupsya mtima ali ndi mphamvu zokolola pafupifupi 170 megapascals, kupanga kukhala oyenera ntchito ndi zolimbitsa mphamvu zofunika.
Ductility
Amawoneka bwino kwambiri, omwe amawapangitsa kuti apangidwe mosavuta m'mawonekedwe osiyanasiyana kudzera munjira monga kugudubuza, kupindika, ndi kupondaponda. Izi zimapangitsa kuti mbale za 5-mndandanda wa alloy zikhale zosunthika kwambiri popanga, chifukwa zimatha kusinthidwa kukhala zigawo zovuta popanda kusweka kapena kusweka.
Kukaniza Kutopa
5-mndandanda wa aluminiyamu aloyi ali ndi kukana kutopa kwabwino. Chikhalidwe ichi ndi chofunikira kwambiri pamagwiritsidwe omwe zinthuzo zimafunika kupirira kutsitsa ndikutsitsa mobwerezabwereza, monga mafakitale apamlengalenga ndi magalimoto. Kupyolera mu chithandizo choyenera cha kutentha ndi chithandizo chapamwamba, moyo wa kutopa wa ma alloyswa ukhoza kuwonjezereka.
Kukaniza kwa Corrosion
Chimodzi mwazabwino kwambiri za5-mndandanda wa aluminiyamu aloyi mbalendi kukana kwawo kwakukulu kwa dzimbiri. Kukhalapo kwa magnesium mu alloy kumapanga gawo loteteza la oxide pamwamba, lomwe limakhala ngati chotchinga motsutsana ndi zinthu zachilengedwe monga chinyezi, mchere, ndi mankhwala. Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo am'madzi, kumanga ma facade, ndi zida zakunja zomwe zimakumana ndi chilengedwe kwa nthawi yayitali.
Malo Ofunsira
Aerospace Industry
M'munda wamlengalenga, mbale za 5-series alloy zimagwiritsidwa ntchito m'mapangidwe a ndege, kuphatikiza mapanelo a fuselage, zigawo za mapiko, ndi mbali zamkati. Kuchuluka kwawo kwamphamvu ndi kulemera kwawo, kukana kwa dzimbiri, komanso kukana kutopa kumawapangitsa kukhala zida zofunika kwambiri zochepetsera kulemera kwa ndege ndikuwonetsetsa chitetezo ndi kulimba.
Makampani Agalimoto
Amagwiritsidwanso ntchito kwambiri m'makampani opanga magalimoto. Ma 5-series alloys amagwiritsidwa ntchito kupanga matupi agalimoto, zitseko, ma hood, ndi mapanelo ena akunja. Maonekedwe abwino a ma alloys awa amalola kupanga zida zamagalimoto zowoneka bwino, ndipo kukana kwawo kwa dzimbiri kumathandizira kukulitsa moyo wautumiki wamagalimoto.
Marine Applications
Chifukwa cha kukana kwawo kwa dzimbiri, mbale za 5-series aluminium alloy ndi chisankho chodziwika bwino pamabomba apamadzi, ma desiki, ndi ma superstructures. Amatha kupirira madera ovuta a m'nyanja, kuphatikizapo kukokoloka kwa madzi a m'nyanja ndi chinyezi chambiri, popanda kuwonongeka kwakukulu.
Ntchito Zomangamanga
Pantchito yomanga, mbale 5 za alloy zimagwiritsidwa ntchito pomanga ma facade, makoma a nsalu, ndi madenga. Kukana kwawo kwa dzimbiri, kuphatikizidwa ndi mawonekedwe owoneka bwino komanso kusavuta kusinthidwa kukhala mawonekedwe osiyanasiyana komanso kumalizidwa kwapamwamba, kumawapangitsa kukhala chinthu chokondedwa pamapangidwe amakono.
Kupanga ndi Kukonza
5-mndandanda wa aluminiyamu alloy mbale nthawi zambiri amapangidwa kudzera mwa kuphatikiza kuponyera, kugudubuza, ndi njira zochizira kutentha. Pambuyo poponya ma alloy ingots, kugudubuzika kotentha kumachitika kuti kugwetse kapangidwe kake ndikuwongolera kufanana kwazinthuzo. Kenako, kugudubuza kozizira kumachitidwa kuti akwaniritse makulidwe omwe amafunidwa ndi kumaliza pamwamba. Njira zochizira kutentha monga kuziziritsa kapena kukalamba kochita kupanga pambuyo pa chithandizo cha kutentha zitha kugwiritsidwa ntchito kupititsa patsogolo makina a alloy.
Kusankha Plate Yoyenera ya 5-Series Alloy
Posankha a5-mndandanda wa aluminiyamu alloy mbalepa ntchito yapadera, zinthu zingapo ziyenera kuganiziridwa. Zinthuzi zikuphatikizapo zofunikira zamakina (monga mphamvu, ductility, ndi kukana kutopa), malo ogwirira ntchito (kaya amatha kuwonongeka), njira yopangira (zofunika za mawonekedwe), ndi mtengo wake. Mwachitsanzo, ngati mphamvu yayikulu komanso kukana kwa dzimbiri kumafunika pakugwiritsa ntchito m'madzi am'madzi, alloy 5083 ikhoza kukhala chisankho choyenera. Kumbali ina, ngati kupangika ndiko kulingalira koyambirira kwa njira yovuta yopondaponda, aloyi yokhala ndi magnesiamu otsika komanso mawonekedwe abwinoko angakhale oyenera.
Pomaliza, 5-series aluminium alloy plates ndi zida zosunthika zogwira ntchito zambiri zomwe zimagwiritsidwa ntchito mosiyanasiyana. Mawonekedwe awo apadera amakina, kukana kwa dzimbiri, komanso mawonekedwe ake amawapanga kukhala chisankho choyenera pamafakitale osiyanasiyana, kuyambira zakuthambo mpaka zomanga. Kumvetsetsa kapangidwe kawo, katundu wawo, ndi kugwiritsa ntchito kwawo kungathandize opanga ndi mainjiniya kupanga zisankho zabwino posankha zida zama projekiti awo.
