I-alloy nganye iqulethe iipesenti ezithile ze-alloying elements ezinika isiseko se-aluminiyam iimpawu ezithile eziluncedo.Ngo-2024 i-aluminiyam ialloy, ezi pesenti ze-elementi zibizwa ngokuba yi-4.4% yobhedu, i-1.5% ye-magnesium, kunye ne-0.6% ye-manganese. amandla aphezulu, njengoko ubhedu, i-magnesium, kunye ne-manganese yandisa kakhulu amandla e-aluminium alloys. Nangona kunjalo, la mandla ane-downside.I-proportion ephezulu yobhedu kwi-2024 i-aluminium inciphisa kakhulu ukuxhathisa kwayo. , intsimbi, i-zinc, i-titanium, njl.), kodwa ezi zinikwe ukunyamezela ngenjongo kuphela kwisicelo somthengi.Ukuxinana kwayo yi-2.77g/cm3 (0.100 lb/in3), iphakame kancinci kune-aluminiyam esulungekileyo (2.7g/cm3, 0.098 lb) /in3) .2024 i-aluminium ilula kakhulu kumatshini kwaye inokusebenza kakuhle, ivumela ukuba inqunywe kwaye ikhutshwe xa ifunwa.
Njengoko sele kukhankanyiwe, ingxubevange 2024 aluminiyam corrode lula ngakumbi kunezinye ingxubevange aluminiyam eninzi. i-aluminiyam yobunyulu okanye enye i-alloy, kwaye ithandwa kakhulu kwiishiti zetsimbi, apho i-alloy yentombi inokuthi ifakwe phakathi kwe-cladding layer. zombini ihlabathi ngenxa ye-alloys ebuthathaka e-corrosive efana ne-2024. Olu phuhliso lwenza i-aluminium ye-2024 ibe luncedo ngakumbi kuba amandla ayo anokuphunyezwa apho i-alloys engenanto iqhele ukuthotywa.
Ezinye ii-alloys ze-aluminium, ezifana ne-2xxx, 6xxx, kunye ne-7xxx series, zinokuqiniswa ngokusebenzisa inkqubo ebizwa ngokuba yi-heat treatment.Inkqubo ibandakanya ukufudumeza i-alloy kwiqondo lokushisa elithile ukuxuba okanye "i-homogenize" izinto ezixutywayo kwisiseko sesinyithi, ngoko Ukucima kwisisombululo ukutshixa izinto endaweni. Eli nyathelo libizwa ngokuba "isisombululo sonyango lobushushu".Ezi zinto azinzanga, kwaye xa i-workpiece ipholile, ikhupha "isisombululo" se-aluminium njengeekhompawundi (umzekelo, iiathom zobhedu ziya kudlula. ngaphandle njenge-Al2Cu) .Ezi zixhobo zokwandisa amandla onke e-alloy ngokusebenzisana ne-aluminium microstructure, inkqubo eyaziwa ngokuba "ukuguga." Ukuqonda isisombululo sonyango lobushushu kunye nenkqubo yokuguga kubalulekile kuba i-aluminium ye-2024 iza kwiindidi ezininzi kwaye inikwe amagama. ezifana 2024-T4, 2024-T59, 2024-T6, njl, kuxhomekeke kwindlela ezi nyathelo zenziwa ngayo.
Uhlobo lwe-2024 aluminiyam yezona mpawu zamandla zibalaseleyo aziveli nje ekubunjweni kwayo, kodwa nakwinkqubo yayo yokunyanga ubushushu. Kukho iinkqubo ezininzi ezahlukeneyo okanye "i-tempering" ye-aluminiyam (inikwe igama elithi -Tx, apho x yinombolo e-1 ukuya kwi-5 inombolo ubude. ), kwaye nangona ziyi-alloy efanayo, zonke zineempawu zazo ezizodwa.Idijithi yokuqala emva kwe "T" ibonisa indlela yonyango olusisiseko lobushushu, kwaye ukhetho lwesibini ukuya kweyesihlanu lubonisa umgangatho othile wokuvelisa.Umzekelo, kwi a 2024-T42 umsindo, i “4″ ibonisa ukuba ingxubevange sisisombululo ubushushu iphathwe kwaye ngokwendalo ubudala, kodwa "2" ibonisa ukuba intsimbi kufuneka ubushushu iphathwe ngumthengi. iya kubonisa kuphela amaxabiso amandla kwi-2024-T4 ye-aluminiyam eshushu ngakumbi.
Kukho iipropathi ezithile zoomatshini ezinokuthi zisetyenziswe ukucacisa ialluminiyamu ialloys. Kwialloys ezinje nge2024 aluminium, eminye imilinganiselo ebalulekileyo ingamandla okugqibela, amandla esivuno, amandla okucheba, amandla okudinwa, kunye nelastiki kunye neshear moduli. Ingcamango malunga nokuchaneka, amandla kunye nokusetyenziswa kwezinto eziphathekayo kwaye zishwankathelwe kwiThebhile 1 ngezantsi.
Amandla esivuno kunye namandla okugqibela yizona zixinzelelo eziphezulu ezibangela ukuguqulwa okungapheliyo kunye nokusisigxina kweesampuli ze-alloy, ngokulandelanayo.Ukufumana ingxoxo enzulu ngakumbi yala maxabiso, zikhululeke ukutyelela inqaku lethu kwi-7075 Aluminium Alloy.Zibalulekile xa i-alloys. zisetyenziselwa kwizicelo ezimileyo apho ukuguqulwa okusisigxina akufanele kwenzeke, njengezakhiwo okanye izixhobo zokhuseleko.2024 i-aluminium inamandla amangalisayo kunye nemveliso ye-469 MPa (68,000 psi) kunye ne-324 MPa (47,000 psi), eyenza ibe nomtsalane kumandla aphezulu. izinto zokwakha ezifana ityhubhu aluminiyam.
Okokugqibela, imodulus elastic kunye neshear modulus ziiparameters ezibonisa indlela "elastic" into enikiweyo ideform.Banika umbono olungileyo wokuchasana kwezinto kuguquko olusisigxina.I-2024 aluminium alloy ine-elastic modulus ye73.1 GPa. (10,600 ksi) kunye nemodyuli yokucheba ye-28 GPa (4,060 ksi), engaphezulu nangaphezulu kunezinye iialloyi zenqwelo-moya eziphezulu ezifana ne-7075 aluminium.
Uhlobo lwe-2024 aluminiyam lunobuchule obugqwesileyo, ukusebenza kakuhle, amandla aphezulu, kwaye inokugqunywa ukuxhathisa ukubola, iyenze ibe lolona khetho lubalaseleyo kwizicelo zenqwelomoya kunye nezithuthi.
