Aloyi iliyonse imakhala ndi magawo enaake a zinthu zomwe zimapatsa maziko a aluminiyamu zinthu zina zopindulitsa. kulimba kwambiri, monga mkuwa, magnesium, ndi manganese kumawonjezera kwambiri mphamvu ya zitsulo zotayidwa. , chitsulo, zinki, titaniyamu, etc.), koma izi zimangoperekedwa mwadala kulolerana ndi pempho la wogula. /in3) .2024 aluminiyamu ndi yosavuta kugwiritsa ntchito makina ndipo ili ndi makina abwino, omwe amalola kuti adulidwe ndi kutulutsidwa akafunika.
Monga tanenera, anabala 2024 zotayidwa dzimbiri dzimbiri mosavuta kuposa zina zotayidwa zina zambiri zotayidwa. zotayidwa woyera kapena aloyi wina, ndipo ndi wotchuka kwambiri atavala zitsulo mapepala, kumene aloyi namwali akhoza sandwiched pakati pa cladding layers.Clad zotayidwa ndi otchuka kwambiri kuti osiyanasiyana mankhwala AlClad apangidwa ndi ambiri ntchito kupereka zabwino kwambiri. maiko onse chifukwa cha zosakaniza zofooka zowononga monga 2024. Kukulaku kumapangitsa 2024 aluminiyamu kukhala yothandiza kwambiri chifukwa mphamvu zake zitha kupezeka pomwe ma aloyi opanda kanthu amatha kunyonyotsoka.
Ma aluminiyamu ena, monga 2xxx, 6xxx, ndi 7xxx mndandanda, akhoza kulimbikitsidwa pogwiritsa ntchito njira yotchedwa kutentha kutentha. Njirayi imaphatikizapo kutenthetsa alloy ku kutentha kwapadera kusakaniza kapena "homogenize" zinthu zomwe zimapangidwira muzitsulo zoyambira, ndiye Kuzimitsa mu njira yotsekera zinthu m'malo mwake. Sitepe iyi imatchedwa "mankhwala otentha otentha". Zinthuzi ndi zosakhazikika, ndipo chogwirira ntchito chikazizira, chimatuluka muzitsulo za aluminiyamu monga mankhwala (mwachitsanzo, maatomu amkuwa ayamba kugwa. kunja monga Al2Cu) .Mapangidwewa amawonjezera mphamvu zonse za alloy polumikizana ndi aluminium microstructure, njira yotchedwa "kukalamba." Kumvetsetsa yankho la chithandizo cha kutentha ndi ukalamba n'kofunika chifukwa 2024 aluminiyumu imabwera mumitundu yambiri ndipo imapatsidwa mayina. monga 2024-T4, 2024-T59, 2024-T6, etc., kutengera momwe masitepewa amachitikira.
Makhalidwe abwino kwambiri a aluminiyumu a Type 2024 samabwera chifukwa cha kapangidwe kake, komanso kachitidwe kake ka kutentha. Pali njira zambiri zosiyanasiyana kapena "kutenthetsa" kwa aluminiyamu (kupatsidwa dzina -Tx, pomwe x ndi manambala 1 mpaka 5 kutalika kwa manambala. ), ndipo ngakhale ali aloyi yemweyo, onse ali ndi katundu wawo wapadera.Chiwerengero choyamba pambuyo pa "T" chimasonyeza njira yochiritsira kutentha, ndipo chiwerengero chachiwiri mpaka chachisanu chimasonyeza khalidwe lapadera lopangira.Mwachitsanzo, mu a 2024-T42 kupsa mtima, ndi "4" zikusonyeza kuti aloyi ndi yankho kutentha mankhwala ndi okalamba mwachibadwa, koma "2" zikusonyeza kuti zitsulo ayenera kutentha ankachitira ndi wogula. Dongosolo akhoza kukhala zosokoneza, kotero m'nkhani ino ife zidzangowonetsa mphamvu zamphamvu za aluminiyumu yoyambira kwambiri ya 2024-T4.
Pali zida zina zamakina zomwe zingagwiritsidwe ntchito kutchula ma aluminiyamu aloyi. Kwa ma aloyi monga aluminiyamu ya 2024, miyeso ina yofunika kwambiri ndi mphamvu yomaliza, mphamvu zokolola, kumeta ubweya, mphamvu ya kutopa, ndi zotanuka ndi kukameta ubweya moduli. lingaliro la machinability, mphamvu ndi momwe angagwiritsire ntchito zinthuzo ndipo zafotokozedwa mwachidule mu Gulu 1 pansipa.
Mphamvu zokolola ndi mphamvu zomaliza ndizo kupsinjika kwakukulu komwe kumayambitsa kusinthika kosatha komanso kosatha kwa zitsanzo za alloy, motsatana. amagwiritsidwa ntchito pa malo osasunthika kumene kusinthika kosatha sikuyenera kuchitika, monga m'nyumba kapena zipangizo zotetezera.2024 aluminiyamu ili ndi mphamvu zochititsa chidwi kwambiri komanso zokolola za 469 MPa (68,000 psi) ndi 324 MPa (47,000 psi), zomwe zimapangitsa kuti zikhale zokopa chifukwa champhamvu kwambiri. zida zomangamanga monga machubu a aluminium.
Pomaliza, zotanuka modulus ndi kukameta ubweya modulus ndi magawo omwe akuwonetsa momwe "elastic" chinthu chopatsidwa chimapunthira. Amapereka lingaliro labwino la kukana kwa zinthuzo kuti zisinthe mokhazikika. (10,600 ksi) ndi shear modulus ya 28 GPa (4,060 ksi), yomwe ndi yapamwamba kwambiri kuposa ma aloyi ena amphamvu kwambiri a ndege monga 7075 aluminiyamu.
Aluminiyamu yamtundu wa 2024 ili ndi makina abwino kwambiri, ogwira ntchito bwino, olimba kwambiri, ndipo amatha kuvala kuti asachite dzimbiri, zomwe zimapangitsa kukhala chisankho chabwino kwambiri pakugwiritsa ntchito ndege ndi magalimoto.
