I-aluminium-scandium ingxubevangeyi-alloy ye-aluminiyam esebenza kakhulu. Ukongeza inani elincinciscandiumkwi-alloy ye-aluminiyam inokukhuthaza ukulungiswa kweenkozo kunye nokunyusa ubushushu bokubuyisela kwakhona nge-250 ℃ ~ 280 ℃. Ingumhluzi onamandla wengqolowa kunye ne-recrystallization inhibitor esebenzayo kwi-alloys ye-aluminium, enempembelelo ebalulekileyo kwisakhiwo kunye neepropati ze-alloy, iphucula kakhulu amandla ayo, ukuqina, ukusebenza kwe-welding, kunye nokuxhathisa ukubola.Scandiuminesiphumo esihle sokuqinisa ukusabalalisa kwi-aluminiyam, kwaye igcina isakhiwo esizinzileyo esingatshintshiyo kwimeko yokulungiswa okushushu okanye i-annealing. Ezinye ii-alloys ziipleyiti ezicekethekileyo eziqengqelekayo ezibandayo ezinoguquko olukhulu, kwaye zisaqhubeka zisigcina esi sakhiwo nasemva kokufakwa. Impembelelo yokuthintela i-scandium kwi-recrystallization inokuphelisa isakhiwo esihlaziyiweyo kwindawo echaphazelekayo yokushisa ye-weld, kunye nesakhiwo esingaphantsi kwe-matrix sinokutshintshela ngokuthe ngqo kwisakhiwo se-weld ye-weld, ukwenzela ukuba i-welded joints of the scandium-containing I-alloy ye-aluminiyam inamandla aphezulu kunye nokumelana nokubola. Ukuphuculwa kwe-corrosion resistance ye-aluminium alloys nge-scandium nayo ibangelwa ukulungiswa kweenkozo kunye nokuvinjelwa kwenkqubo ye-recrystallization nge-scandium. Ukongeza i-scandium kunokwenza i-aluminium alloy ibe ne-superplasticity elungileyo. Emva konyango lwe-superplastic, ukwandiswa kwe-aluminium alloy malunga ne-0.5%scandiuminokufikelela kwi-1100%. Ngoko ke,i-aluminium-scandium ingxubevangekulindeleke ukuba ibe sisizukulwana esitsha sezinto ezikhaphukhaphu zolwakhiwo lwe-aerospace, inqwelomoya, kunye nolwakhiwo lweenqanawa. IRashiya iye yaphuhlisa ngaphezu kwe-10 yamabanga e-aluminium alloy equlethe i-scandium, esetyenziselwa ukuwelda iindawo zesakhiwo ezithwele umthwalo kwindawo ye-aerospace, i-aviation, kunye neenqanawa, kunye nemibhobho ye-aluminiyam ye-alkaline yendawo yeendaba ezonakalisayo, iitanki zeoyile kaloliwe, kunye nezitshixo. iindawo zesakhiwo koololiwe abanesantya esiphezulu.
I-Scandium equlethe i-alloys ye-aluminium inethemba elibanzi lokusetyenziswa kumacandelo e-high-tech efana nokwakhiwa kweenqanawa, ishishini le-aerospace, iirokethi kunye nemijukujelwa, kunye namandla enyukliya. Ngokongeza amanani omkhondo we-scandium, kuyathenjwa ukuba uthotho lwezixhobo ze-alloy ze-aluminiyam zesizukulwana esitsha ezifana ne-ultra-high-strength kunye ne-high-toughness-high-toughness aluminium alloys, i-alloys ye-aluminium enganyangekiyo, kunye namandla aphezulu. ialloys aluminiyam yokumelana nemitha ye-neutron iya kuphuhliswa ngokwesiseko se-alloys ekhoyo ye-aluminiyam. Ezi ngxubevange ziya kuba nemibono enomtsalane kakhulu yosetyenziso kwi-aerospace, amandla enyukliya, kunye namashishini okwakha iinqanawa ngenxa yeepropathi zazo ezigqwesileyo ezibanzi. Zisenokusetyenziswa nakwizithuthi ezilula kunye noololiwe abahamba ngesantya esiphezulu. Ke ngoko, iialloyi ze-aluminium ezine-scandium ziye zaba yenye into ekhangayo kunye neyona nto ikhuphisanayo ephezulu yokusebenza kwe-aluminium alloy emva kwe-AlLi alloys. ilizwe lam lityebile kwimithombo ye-scandium, kwaye linesiseko esithile sophando kunye nokuveliswa kwemveliso ye-scandium. I-China iseyeyona ndawo iphambili yokuthumela ngaphandle kwe-scandium oxide. Uphando kwiiialloyi zeAlScibaluleke kakhulu kwixesha elidlulileyo kuphuhliso lwemathiriyeli yealluminiyam kulwakhiwo lwelizwe lam lobugcisa obuphezulu kunye nokhuselo lwesizwe. Isenokudlala ngokupheleleyo kwiinzuzo zelizwe lam kwi-scandium kunye nokukhuthaza uphuhliso loshishino lwelizwe lam kunye noqoqosho lwesizwe.
Ukuze ufumane inkcazelo engakumbi malunga Aluminium-Scandium Alloy wamkelekile kuQhagamshelana nathi
