Chiwanikwa chega chega chine zvikamu zvakati zvealloying zvinhu zvinopa base aruminiyamu humwe hunhu hunobatsira.Muna 2024 aruminiyamu alloy, zvikamu zvezvikamu izvi zvinonzi 4.4% copper, 1.5% magnesium, uye 0.6% manganese.Kuparara uku kunotsanangura kuti sei 2024 aluminum ichizivikanwa nokuda kwayo simba rakakwirira, semhangura, magnesium, uye manganese inowedzera simba realuminium alloys.Zvisinei, simba iri rine pasi.Iyo yakawanda yemhangura mu 2024 aruminiyamu inoderedza zvikuru kusagadzikana kwayo kwekuora. , simbi, zingi, titanium, nezvimwewo), asi izvi zvinongopihwa zvine chinangwa kushivirira pachikumbiro chemutengi. Density yayo i2.77g/cm3 (0.100 lb/in3), yakakwira zvishoma pane pure aluminum (2.7g/cm3, 0.098 lb /in3) .2024 aruminiyamu iri nyore kwazvo kugadzira uye ine machinability yakanaka, ichibvumira kuti ichekwe uye iwedzere kana ichidikanwa.
Sezvambotaurwa, akashama 2024 aruminiyamu alloys corrode nyore kupfuura mamwe akawanda aruminiyamu alloys.Manufacturers vanosvika kumativi ichi ne coating aya anokanganisa alloys pamwe layer ye simbi isingadziviriri (inonzi "galvanizing" kana "cladding").Kupfeka uku dzimwe nguva yakakwirira- purity aluminium kana kunyange imwe alloy, uye inonyanya kufarirwa mumashizha esimbi akafukidzwa, apo mhandara inogona kuiswa pakati pezvikamu zvekuvhara.Clad aluminium yakakurumbira zvokuti mhando yezvigadzirwa zveAlClad zvakagadzirwa uye zvakashandiswa zvakanyanya kupa zvakanakisisa. nyika mbiri kune alloys asina simba ekuora akadai sa 2024. Kusimukira uku kunoita kuti 2024 aruminiyamu inyanyo batsira nekuti simba rayo rinogona kuwanikwa uko maalloys akashama anowanzo kuderera.
Mamwe aruminiyamu alloys, akadai se2xxx, 6xxx, uye 7xxx series, anogona kusimbiswa achishandisa nzira inonzi heat treatment.Iyo nzira inosanganisira kupisa alloy kune imwe tembiricha yekusanganisa kana "homogenize" iyo alloying element mu base simbi, ipapo. Kudzima mukugadzirisa kukiya zvinhu panzvimbo. Danho iri rinonzi "solution heat treatment".Zvinhu izvi hazvina kugadzikana, uye kana workpiece yatonhora, inonaya kubva mualuminium "solution" semakomitani (somuenzaniso, maatomu emhangura achanaya. kunze seAl2Cu) .Makomponi aya anowedzera simba rose realloy kuburikidza nekubatana nealuminium microstructure, chirongwa chinozivikanwa se "kuchembera."Kunzwisisa mhinduro yekupisa kupisa uye kukwegura kwakakosha nokuti 2024 aluminium inouya mumhando dzakawanda uye inopiwa mazita. se2024-T4, 2024-T59, 2024-T6, zvichingodaro, zvichienderana nekuti matanho aya anoitwa sei.
Type 2024 aruminiyamu yakanakisa simba hunhu hunouya kwete kubva mukuumbwa kwayo chete, asiwo kubva mukuita kwayo kupisa-kupisa. Kune akawanda akasiyana maitiro kana "kupisa" kwealuminium (yakapihwa zita -Tx, apo x inhamba 1 kusvika 5 digit refu. ), uye kunyange zvazvo ari alloy imwe chete, vose vane zvinhu zvavo zvakasiyana-siyana.Idijiti yekutanga mushure me "T" inoratidza nzira yekurapa yekupisa, uye inosarudzwa yechipiri kusvika kune yechishanu inoratidza hutsika hwekugadzira.Somuenzaniso, mu a 2024-T42 hasha, a "4" inoratidza kuti alloy ndiyo mhinduro kupisa kubatwa uye zvakasikwa vakwegura, asi "2" inoratidza kuti simbi inofanira kupisa kurapwa nemutengi.The system inogona kuvhiringidza, saka munyaya ino isu inongoratidza kukosha kwesimba kune yakanyanya kutsamwiswa 2024-T4 aluminium.
Kune mamwe ma mechanic properties anogona kushandiswa kutsanangura aluminum alloys.Kune alloys akadai se2024 aruminiyamu, mamwe mayero akakosha isimba rekupedzisira, goho simba, kugera simba, kuneta simba, uye elastic uye shear moduli.Izvi zvakakosha zvinopa pfungwa nezve machinability, simba uye zvinogona kushandiswa kwezvinhu uye zvakapfupikiswa muTafura 1 pazasi.
Kusimba kwegoho uye kusimba kwekupedzisira ndiko kudzvinyirira kwakanyanya kunokonzera kusingagumi uye kusingagumi deformation yealloy specimens, zvakateerana.Kuti uwane kukurukurirana kwakadzama kwezvinokosha izvi, inzwa wakasununguka kushanyira chinyorwa chedu pa7075 Aluminium Alloy.Izvo zvakakosha kana alloys. anoshandiswa mune static applications apo zvachose deformation haifaniri kuitika, zvakadai muzvivako kana midziyo yekuchengetedza.2024 aluminium ine inoshamisa yekupedzisira uye inobereka simba re 469 MPa (68,000 psi) uye 324 MPa (47,000 psi), zvichiita kuti iwedzere kusimba kwepamusoro-simba. zvimiro zvakaita sealuminium tubing.
Chekupedzisira, elastic modulus uye shear modulus ma paramita anoratidza kuti "elastic" chinhu chakapihwa chinokanganisa sei. Ivo vanopa pfungwa yakanaka yekupokana kwechinhu kushanduka zvachose. Iyo 2024 aluminium alloy ine elastic modulus ye73.1 GPa. (10,600 ksi) uye shear modulus ye28 GPa (4,060 ksi), iyo yakatokwirira kupfuura mamwe maaloyi endege akasimba se7075 aruminiyamu.
Type 2024 aluminium ine yakanakisa machinability, yakanaka kushanda, yakasimba simba, uye inogona kupfekedzwa kudzivirira ngura, zvichiita kuti ive sarudzo yakanaka kwazvo kune ndege nemotokari yekushandisa.
