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 agoqwe anokuguqulwa okukhulu, 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. I-aluminium alloy alloy esekelwe ku-alloy ekhona ye-aluminium, njengamandla aphezulu kakhulu kanye nokuqina okuphezulu kwe-aluminium alloy, i-alloy ye-aluminium engagqwali, amandla aphezulu e-neutron irradiation resistant aluminium alloy nokunye.Lawa ma-alloys azoba ne-alloy ekhangayo kakhulu. ithemba lokufaka isicelo ku-aerospace, amandla enuzi kanye nezimboni zokwakha imikhumbi ngenxa yezakhiwo zazo ezinhle kakhulu ezibanzi, futhi zingasetshenziswa ezimotweni ezilula nezitimela ezinesivinini esikhulu. Ngakho-ke, ingxube ye-aluminium equkethe i-scandium isibe 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 oyinhloko we i-scandium oxide. Kubaluleke kakhulu ukuthuthukiswa kwe-aluminium alloy materials zokwakha ubuchwepheshe obusezingeni eliphezulu kanye nezwe lonke e-China, futhi i-AlSc ingakwazi ukudlala ngokugcwele izinzuzo zezinsiza ze-scandium e-China futhi ikhuthaze ukuthuthukiswa kwemboni ye-scandium nomnotho wezwe e-China. .
