Ikhentiyamuyinto yokushintsha kanye nenye yezinto zomhlaba ezingandile. Inezakhiwo ezinhle kakhulu njengokuthambitheka, izakhiwo zamakhemikhali ezisebenzayo, ezempi eziphakeme kanye namandla aphansi aphansi. Uma ungezwe kuma-aluminium alloys, kungathuthukisa kakhulu amandla, ubulukhuni kanye nezinye izakhiwo zama-alloys. Kunguhlobo olusha lwe-Trace Element yokuthuthukiswa kwamandla aphezulu, ama-aluminium amelana nokushisa aphezulu amelana ne-torrosion. Njengoba iphuzu lokuncibilika leScandium liphezulu kakhulu, ku-1541 ° C, ngenkathi iphuzu lokuncibilika le-aluminium lingama-660 ° C kuphela, ngakho-ke iScandium izinsimbi zihluke kakhulu, ngakho-ke iScandium kufanele ingezwe ku-aluminium alloy ngesimo se-alloy ephakathi. Ngakho-ke,I-Aluminium-Scandium Intermediate Aloyizinto ezibalulekile eziluhlaza zokulungiselelaI-Aluminium-Scandium Alloys.
Ukungeza amanani we-Scandium (0.15 ~ 0.5WT%) kuya ku-Aluminium Alloys angadlala indima enhle yokuqalisa. Okokuqala, ingahlaziya kakhulu okusanhlamvu kwama-tast alloys futhi iyisihlalo sokuhlanza esinamandla sama-aluminium alloys. Okwesibili, kungakhuphula izinga lokushisa kabusha kabusha ngo-250 ℃ ~ 280 ℃ ~ 280 ℃ ~ 280 ~ 280 ~ 280, susa isakhiwo esiphindaphindwayo endaweni yokushisa kwe-weld, futhi ukwakheka okuqondile kwe-matrix kungavimbela ukuqhekeka okushisayo futhi kuthuthukise ukumelana nokukhathala kwe-aluminium alloy. Kuyinto esebenza ngempumelelo yokuvuselela kabusha i-Aluminium Alloys futhi inomphumela obalulekile esakhiweni nasezakhiweni ze-alloy, ukuthuthukisa kakhulu amandla alo, ukumelana nokushisa, ukumelana nokushisa kanye nokumelana nokulimala kwemisebe ye-neutron. Njengamanje, kuyaziwa ukuthi amandla kaI-Aluminium-Scandium AlloyUngafinyelela ngaphezu kwe-750mpa, futhi i-modulus e-elastic idlula i-100gpa, okuphezulu kwama-30% kunalokho kwama-alluminium endabuko. Okwesithathu, kungadlala indima enhle ekuqiniseni ukuxhaxha, ukulondolozwa kwesakhiwo esizinzile esingesihle esimweni sokusebenza okushisayo noma ukwelashwa okuvuselayo, futhi sinezimpawu zokusebenza okuhle okushisayo kanye nokuqina okuphezulu okushisayo. Okwesine, kungenza ama-alloys we-aluminium abe nokuhle kakhulu. Ngemuva kokwelashwa okucacile, ukunwebeka kwe-aluminium alloys nge-0.5% Scandium engezwe ingafinyelela ku-1100%.
Ngokusekelwe kwizakhiwo ezinhle kakhulu zemishini ze-Aluminium-Scandium Alloys ezishiwo ngenhla, zibhidliza ibhodlela lamandla we-Aluminium Allunum, futhi namanje ukulondolozwa kwamandla amasha, imikhiqizo eyenziwe nge-Aluminium-Scandium Alloys iqale ukuvela ezimakethe zamazwe athuthukile njengeYurophu nase-United States. I-Aluminium-Scandium Alloys uhlobo lokusebenza okuphezulu kwe-aluminium entsha ngamandla aphezulu, ubulukhuni obuphakeme, nesisindo esikhanyayo. Ziyizinto ezilungele izinto zezakhiwo zezinkukhu, ozimele zebhayisekili, amakilabhu wegalofu, njll. Bakhona futhi isizukulwane esisha se-aluminium alloy izinto zokwakha izinkambu zokusikwa kwezivikelo zikazwelonke kanye nemikhumbi yezempi, izindiza, i-aerospace, amandla enuzi, nezikhali. Zisetshenziselwa ikakhulukazi izingxenye zesakhiwo se-welding zokuthwala umthwalo we-aerospace, izindiza, nemikhumbi, kanye namapayipi we-aluminium alloy wezindawo zemidiya ye-alkaline ezonakalisayo, amathangi e-railway kawoyela, kanye nezingxenye ezibalulekile zesakhiwo sezitimela eziphakeme. Zisetshenziswa kabanzi e-Aerospace, ezokuhamba, embonini yenuzi, i-elekthronikhi, iziqukathi zokupakisha, nezinye izinkambu.
Njengamanje, kunezinhlobo ezingaphezu kwenkulungwane zezinto zokwakha ze-aluminium emhlabeni, ezenze iminikelo emikhulu enqubekela phambili yabantu. Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nokwenza ngcono amazinga okuphila, izwe lami lidinga ukuthuthukisa ama-alloys amasha aphezulu aclemininum. Ukuthuthukiswa kwama-alloys aphakathi nendawo eScandium-aluminium aphakathi nendawo angabeka isisekelo esiqinile sokuthuthukiswa kwalezi zinto zokusebenza okuphezulu, ukukhuthaza kakhulu ukuthuthukiswa komkhakha we-aluminium wezwe lami kanye nemboni ye-scandium, futhi kugqugquzelwe ukuhlanganiswa komkhakha we-aluminium wezwe lami. Ngakho-ke, iphrojekthi yokulungiselela ye-Aluminium-Scandium (Intermediate) Alloy ibaluleke kakhulu kanye nesidingo, futhi iyindlela ebalulekile yokuthuthukiswa kwezinto zokwakha i-aluminium ngokuzayo.
