Iqondo lobushushu eliqengqelekayo leengxubevange ze-aluminiyam lihlala liphezulu kunobushushu be-annealing. Ukuqengqeleka okushushu yindlela yokucubungula ebandakanya ukuguqulwa kweplastiki yentsimbi kumaqondo obushushu aphakamileyo ukufezekisa ubume obufunwayo kunye neempawu.. Iqondo lobushushu elishushu lingaphezulu kobushushu be-solidus yealloyi, ukuqinisekisa iplastiki eyaneleyo yokuguqula. Kuba ialloys aluminiyam, iqondo lobushushu eliqengqelekayo lidla ngokuwela phakathi koluhlu oluphezulu lobushushu, rhoqo ukugqitha 500 Izidanga zeCelsius, kuxhomekeke ekubunjweni kwe-alloy kunye neempawu.
Ipleyiti yeAluminiyam/iphepha umgca wokuvelisa inkqubo eshushu yokuqengqeleka
Ukuhlaziya, kwelinye icala, yinkqubo yonyango lobushushu emva kokuqengqeleka okushushu (kwaye ngamanye amaxesha iinkqubo zokusebenza ezibandayo) ejolise ekuphuculeni ukwakheka kwekristale kunye neepropathi zetsimbi ngokufudumeza kwiqondo lobushushu elisezantsi kwaye emva koko uyipholise kancinci, ngaloo ndlela kuphelisa uxinzelelo lwangaphakathi kunye nokwandisa i-ductility. Ubushushu be-annealing buhlala busezantsi kunobushushu obuqengqelekayo, ngokubanzi ngaphantsi kobushushu be-solidus ye-alloy, kwaye iyahluka ngokusekelwe kwi-alloy ethile kunye nokusebenza okufunayo.
Apha ngezantsi kukho itafile eyenziwe lula eshwankathela amaqondo obushushu obushushu bothotho olwahlukeneyo lwealluminiyam.. Le theyibhile ijolise ekunikezeni ireferensi ekhawulezayo kudederhu lweqondo lobushushu eliqhelekileyo lokufunxa olufanelekileyo kwiindidi ezahlukeneyo zengxubevange yealuminiyam.. Khumbula, ubushushu obuchanekileyo kunye nenkqubo inokwahluka ngokusekwe kulwakhiwo oluthile lwealloyi kunye neempawu zokugqibela ezinqwenelekayo.
Aluminiyam ingxubevange Series | Inkcazo | Uluhlu lweqondo lobushushu |
1xxx Series | IAluminiyam ecocekileyo | 345°C ukuya kuma-415°C (650°F ukuya kuma-775°F) |
2xxx Series | I-Aluminiyam-i-Copper Alloys | 413°C ukuya kuma-483°C (775°F ukuya kuma-900°F) |
3xxx Series | I-Aluminiyam-Manganese Alloys | 345°C ukuya kuma-410°C (650°F ukuya kuma-770°F) |
4xxx Series | Aluminiyam-Silicon Alloys | Iyahluka; bhekisa kwi-alloy ethile |
5xxx Series | Aluminiyam-Magnesium Alloys | 345°C ukuya kuma-410°C (650°F ukuya kuma-770°F) |
6xxx Series | I-Aluminiyam-Magnesium-Silicon Alloys | 350°C ukuya kuma-410°C (660°F ukuya kuma-770°F) |
7xxx Series | I-Aluminiyam-Zinc Alloys | 343°C ukuya kuma-477°C (650°F ukuya kuma-890°F) |
8xxx Series | Aluminiyam alloys kunye nezinye izinto | Iyahluka ngokubanzi; rhoqo ngama-345°C ukuya kuma-415°C (650°F ukuya kuma-775°F) kwiialloys ezithile ezifana 8011 |
Le theyibhile inika umbono obanzi. Ngeemeko ezichanekileyo zokufunxa, kubandakanywa amaxesha okufunxa kunye namazinga okupholisa, ukubonisana neenkcukacha zezinto eziphathekayo okanye ingcali ye-metallurgical iyacetyiswa. Iimfuno ezithile zinokuchaphazela kakhulu iipropathi zoomatshini kunye nokufaneleka kwezicelo ezahlukeneyo.
Ukufakwa kweekhoyili ze-aluminiyam yinkqubo eqhelekileyo yonyango lobushushu
Isishwankathelo, iqondo lobushushu elishushu liphezulu kunobushushu bokuhlala ngenxa yokuba ukuqengqeleka okushushu kufuna ukuba intsimbi ibe yiplastiki eyaneleyo yokuguqula amaqondo obushushu aphakamileyo., ngelixa i-annealing igxile ekwandiseni ubume bekristale kunye neepropathi kwaye iqhele ukwenziwa kumaqondo obushushu asezantsi.
