Waxqabadka Sare ee Aluminium Aloy: Al-Sc Alloy

Al-Sc alloy waa nooc ka mid ah aluminium aluminium tayo sare leh.Waxaa jira dhowr siyaabood oo lagu hagaajin karo waxqabadka aluminium aluminium, kuwaas oo xoojinta micro-alloying iyo xoojinta ay tahay goobta xuduudaha ee cilmi-baarista aluminium-waxqabadka sare ee cilmi-baarista 20-kii sano ee la soo dhaafay.

Barta dhalaalka ee scandium waa 1541 ℃, kan aluminiumkuna waa 660℃, marka scandium waa in lagu daraa daawaha aluminium qaab ah aluminium aluminium ah, taas oo ah alaabta ceeriin ee muhiimka ah ee diyaarinta daawaha aluminium ka kooban scandium.Waxaa jira dhowr habab oo lagu diyaariyo aluminium sare, sida habka doping, fluoride scandium, habka dhimista kulaylka birta ee birta ee scandium, habka milixda dhalaalaysa iyo wixii la mid ah."

Habka doping-ku waa in si toos ah loogu daro biraha birta ah ee aluminium aluminium, taas oo qaali ah, luminta gubasho ee habka dhalada iyo qiimaha sare ee aluminiumka

Foloraydhka sunta ah ee loo yaqaan 'Hydrogen fluoride' waxaa loo isticmaalaa diyaarinta scandium fluoride iyadoo loo marayo habka dhimista kulaylka birta ee scandium fluoride, kaas oo leh qalab adag iyo heerkulka hoos u dhigista kulaylka sare ee birta.

Heerka soo kabashada ee scandium by dhimista kulaylka birta ee scandium oxide waa kaliya 80%;

Qalabka milixdu dhalaalayso ee elektiroonigga ah waa mid adag oo heerka beddelashaduna maaha mid sarreeya.

Isbarbardhigga iyo xulashada ka dib, waxaa aad ugu habboon in la diyaariyo Al-Sc master alloy adigoo isticmaalaya ScCl cusbada dhalaalaysa ee Al-Mg habka dhimista kulaylka.

Adeegsada:

Ku darista scandium daawaha aluminiumku waxay kor u qaadi kartaa sifaynta hadhuudhka waxayna kordhin kartaa heerkulka recrystallization 250℃~280℃.Waa nadiifiye awood leh iyo dib-u-kicinta wax ku ool ah ee aluminium alloy, kaas oo saameyn muuqata ku leh th.e qaab dhismeedka iyo sifooyinka daawaha oo si weyn u wanaajisaa xooggiisa, engegnaantiisa, weldability iyo iska caabin daxalka.

Scandium waxay leedahay saameyn wanaagsan oo xoojinta aluminium, waxayna ilaalisaa qaab-dhismeed deggan oo aan dib-u-crystalized ahayn oo ku saabsan shaqada kulul ama daawaynta.Alloys-yada qaarkood waa go'yaal qabow oo duuban oo leh cillad weyn, kuwaas oo weli sii wada dhismahan xitaa ka dib marka la tirtiro.Joojinta scandium on recrystallization waxay baabi'in kartaa qaab dhismeedka recrystallization ee aagga kulaylka saameeyay ee alxanka, Qaab dhismeedka subgrain ee matrix si toos ah loogu wareejin karaa qaab-dhismeedka sida-kabka ah ee alxanka, taas oo ka dhigaysa wadajirka welded ee daawaha aluminium ka kooban scandium leeyihiin. xoog sare iyo iska caabin daxalka.

Saamaynta scandium ee caabbinta daxalka ee aluminium aluminium sidoo kale waxaa sabab u ah sifaynta hadhuudhka iyo joojinta habka dib-u-crystalization.

Ku darida scandium waxay sidoo kale ka dhigi kartaa aluminium aluminiumku inuu yeesho superplasticity wanaagsan, iyo fidinta aluminium aluminium leh 0.5% scandium waxay gaari kartaa 1100% ka dib daaweynta superplastic.

Sidaa darteed, Al-Sc alloy waxaa la filayaa inay noqoto jiil cusub oo ah qalabka qaabdhismeedka fudud ee hawada, duulista iyo warshadaha maraakiibta, kuwaas oo inta badan loo isticmaalo alxanka qaybaha qaab dhismeedka aerospace, duulista iyo markabka, tuubooyinka daawaha aluminium ee deegaanka daxalka alkaline dhexdhexaad ah, Haamaha saliidda tareenka, qaybaha muhiimka ah ee dhismaha tareenada xawaaraha sare leh, iwm

Rajada codsiga:

Aluminium aluminium ah oo Sc-ku jira waxay leedahay rajada codsiga ballaaran ee waaxaha farsamada sare sida markabka, warshadaha hawada sare, gantaalada iyo gantaalaha, tamarta nukliyeerka, iwm Aluminium aluminium ah oo ku salaysan aluminiumka aluminium ee jira, sida xoogga aadka u sarreeya iyo aluminium aluminium adag oo sarreeya, aluminium aluminium ah oo u adkaysta daxalka, tamarta sare ee neutron-ka ee u adkaysta aluminium aluminium iyo wixii la mid ah. Rajada codsiga hawada, tamarta nukliyeerka iyo warshadaha dhismaha maraakiibta sababtoo ah sifooyinkooda dhamaystiran oo aad u wanaagsan, waxaana sidoo kale loo isticmaali karaa baabuurta fudud iyo tareenada xawaaraha sare leh.Sidaa darteed, daawaynta aluminium-ka kooban ee scandium-ka ayaa noqotay wax soo jiidasho leh oo ugu tartan badan wax-qabadka aluminium aluminium qaab-dhismeedka ka dib markii AlLi alloy.China waa hodan ku khayraadka scandium oo uu leeyahay aasaas gaar ah cilmi-baarista scandium iyo wax soo saarka warshadaha, kaas oo weli ah dhoofiyaha ugu weyn ee scandium oxide.Waa muhiimad waqti-qaadasho ah si loo horumariyo agabka aluminiumka aluminiumka ah ee loogu talagalay teknoolojiyadda sare iyo dhismaha difaaca qaranka ee Shiinaha, waxayna AlSc siin kartaa ciyaar buuxda faa'iidooyinka kheyraadka scandium ee Shiinaha iyo kor u qaadista horumarinta warshadaha scandium iyo dhaqaalaha qaranka ee Shiinaha. .
