Ingxubevange Ye-Aluminium Esebenza Kakhulu: I-Al-Sc Ingxubevange

Ingxubevange ye-Al-Sc iwuhlobo lwengxube ye-aluminium esebenza kahle kakhulu. Kunezindlela eziningana zokuthuthukisa ukusebenza kwe-aluminium alloy, phakathi kwazo ukuqinisa i-micro-alloying kanye nokuqina kuyinkambu yemingcele yocwaningo lwe-aluminium alloy olusebenza kahle kakhulu eminyakeni yamuva ye-20.

Indawo encibilikayo ye-scandium ingu-1541℃, kanti eye-aluminium ingu-660 ℃, ngakho-ke i-scandium kufanele yengezwe ku-aluminium alloy ngendlela ye-master alloy, okuwukhiye oyinhloko wokulungisa ingxube ye-aluminium equkethe i-scandium. Kunezindlela eziningana zokulungisa ama-alloys ayinhloko, njenge-doping method, i-scandium fluoride, indlela yokunciphisa ukushisa kwensimbi ye-scandium oxide, indlela ye-electrolysis kasawoti encibilikisiwe nokunye. “

Indlela ye-doping ukufaka ngokuqondile i-scandium yensimbi ku-aluminium alloy, ebiza kakhulu, ukulahlekelwa okuvuthayo enqubweni yokuncibilika kanye nezindleko eziphezulu ze-master alloy.

I-hydrogen fluoride enobuthi isetshenziswa ekulungiseni i-scandium fluoride ngensimbi yokunciphisa ukushisa kwe-scandium fluoride, enemishini eyinkimbinkimbi kanye nezinga lokushisa eliphezulu lokunciphisa ukushisa kwensimbi.

Izinga lokubuyisela i-scandium ngokunciphisa ukushisa kwensimbi ye-scandium oxide yi-80% kuphela;

Idivayisi ye-electrolysis kasawoti encibilikisiwe iyinkimbinkimbi futhi izinga lokuguqulwa aliphezulu.

Ngemva kokuqhathanisa nokukhetha, kufaneleka kakhulu ukulungisa i-Al-Sc master alloy ngokusebenzisa i-ScCl encibilikisiwe kasawoti e-Al-Mg indlela yokunciphisa ukushisa.

Isebenzisa:

Ukwengeza i-trace scandium ku-aluminium alloy kungakhuthaza ukucolisiswa okusanhlamvu futhi kukhuphule izinga lokushisa kabusha ngo-250.℃~280℃. Kuyi-refiner enamandla okusanhlamvu kanye ne-recrystallization inhibitor esebenzayo ye-aluminium alloy, enethonya elisobala ku-th.e isakhiwo kanye izakhiwo ingxubevange futhi ithuthukisa kakhulu amandla ayo, ubulukhuni, weldability kanye ukugqwala ukumelana.

I-Scandium inomphumela omuhle wokuqinisa ukuhlakazeka ku-aluminium, futhi igcina isakhiwo esizinzile esingavuselelwa kabusha ekusebenzeni okushisayo noma ekwelashweni kwe-anneal. Amanye ama-alloys angamashidi abandayo agoqelwe ane-deformation enkulu, asagcina lesi sakhiwo ngisho nangemva kokudonsa. Ukuvinjelwa kwe-scandium ku-recrystallization kungaqeda ukwakheka kabusha kwe-recrystallization endaweni ethintekile ekushiseni, Isakhiwo se-subgrain se-matrix singadluliselwa ngokuqondile esakhiweni se-as-cast se-weld, okwenza i-altare ehlanganisiwe ye-aluminium alloy equkethe i-scandium ibe amandla aphezulu kanye nokumelana nokugqwala.

Umthelela we-scandium ekuphikiseni ukugqwala kwe-aluminium alloy nakho kungenxa yokulungiswa okusanhlamvu kanye nokuvinjwa kwenqubo ye-recrystallization.

Ukwengezwa kwe-scandium nakho kungenza ingxubevange ye-aluminium ibe ne-superplasticity enhle, futhi ukunwetshwa kwe-aluminium alloy nge-0.5% scandium kungafinyelela ku-1100% ngemuva kokwelashwa kwe-superplastic.

Ngakho-ke, ingxubevange ye-Al-Sc kulindeleke ukuthi ibe isizukulwane esisha sezinto zokwakha ezingasindi zezimboni ze-aerospace, zezindiza nezemikhumbi, ezisetshenziselwa kakhulu ukushisela izingxenye zesakhiwo se-aerospace, izindiza kanye nomkhumbi, amapayipi e-aluminium alloy for alkaline corrosive medium environment, amathangi kawoyela kaloliwe, izingxenye ezibalulekile zesakhiwo sezitimela ezihamba ngesivinini esikhulu, njll

Ithemba lokufaka isicelo:

I-aluminium alloy equkethe i-Sc inethuba elibanzi lokufaka isicelo eminyangweni yobuchwepheshe obuphezulu njengomkhumbi, imboni ye-aerospace, rocket ne-missile, amandla enuzi, njll. Ngokungeza i-trace scandium, kunethemba lokuthuthukisa uchungechunge lwesizukulwane esisha sokusebenza okuphezulu. Ingxubevange ye-aluminium esekelwe kungxube ye-aluminium ekhona, njengamandla aphezulu kanye nokuqina okuphezulu kwe-aluminium alloy, amandla aphezulu Ingxubevange ye-aluminiyamu engagqwali, ingxubevange ye-aluminiyamu enamandla amakhulu e-neutron ukumelana nokunye nokunye.Lezi zingxubevange zizoba nethuba elikhangayo lokufaka isicelo endaweni yendiza, amandla enuzi kanye nezimboni zokwakha imikhumbi ngenxa yezakhiwo zazo ezinhle kakhulu ezibanzi, futhi zingasetshenziswa nasezimotweni ezilula. nezitimela ezinesivinini esikhulu. Ngakho-ke, ingxubevange ye-aluminium equkethe i-scandium isiphenduke enye into ekhangayo futhi encintisana kakhulu yokusebenza okuphezulu kwe-aluminium alloy impahla yesakhiwo ngemuva kwe-AlLi ingxubevange.I-China inothile ngezinsiza ze-scandium futhi inesisekelo esithile socwaningo lwe-scandium nokukhiqizwa kwezimboni, okusengumthengisi ophambili we i-scandium oxide. Kubaluleke kakhulu ukuthuthukiswa kwe-aluminium alloy materials zokwakha ubuchwepheshe obusezingeni eliphezulu kanye nezwe lonke e-China, futhi i-AlSc inganikeza ukudlala ngokugcwele izinzuzo zezinsiza ze-scandium e-China futhi ikhuthaze ukuthuthukiswa kwemboni ye-scandium nomnotho wezwe e-China. .
