Imikorere Ihanitse ya Aluminiyumu: Al-Sc Alloy

Imikorere Ihanitse ya Aluminiyumu: Al-Sc Alloy

Al-Sc alloy ni ubwoko bwimikorere ya aluminiyumu. Hariho uburyo bwinshi bwo kunoza imikorere ya aluminiyumu, muribwo mikoro-mikorobe ikomeza kandi igakomera ni umupaka wubushakashatsi bukomeye bwa aluminium alloy mu myaka 20 ishize.

Ingingo yo gushonga ya scandium ni 1541 and, naho iya aluminium ni 660 ℃, bityo rero scandium igomba kongerwamo amavuta ya aluminiyumu mu buryo bwa master alloy, akaba ari ibikoresho by'ibanze byo gutegura aluminiyumu irimo scandium. Hariho uburyo bwinshi bwo gutegura ibinyobwa bisembuye, nkuburyo bwa doping, fluoride scandium, scandium oxide ibyuma bigabanya ubushyuhe bwumuriro, uburyo bwumunyu wa electrolysis yumunyu nibindi. “

Uburyo bwa doping nuburyo bwo kongeramo ibyuma scandium mubyuma bya aluminiyumu, bihenze, gutwika igihombo mugikorwa cyo gushonga hamwe nigiciro kinini cya master alloy

Ubumara bwa hydrogène fluoride ikoreshwa mugutegura fluoride ya scandium hakoreshejwe uburyo bwo kugabanya ubushyuhe bwumuriro wa scandium fluoride, ifite ibikoresho bigoye hamwe nubushyuhe bwo hejuru bwo kugabanya ubushyuhe bwumuriro

Igipimo cyo kugarura scandium ukoresheje ibyuma bigabanya ubushyuhe bwa scandium oxyde ni 80% gusa;

Igikoresho cyumunyu wa elegitoroniki ya electrolysis iragoye kandi igipimo cyo guhinduka ntabwo kiri hejuru.

Nyuma yo kugereranya no gutoranya, birakwiye cyane gutegura Al-Sc master alloy ukoresheje umunyu wa ScCl ushongeshejwe Al-Mg uburyo bwo kugabanya ubushyuhe.

Ikoreshwa:

Ongeramo transe scandium kuri aluminiyumu irashobora guteza imbere gutunganya ingano no kongera ubushyuhe bwa 250℃~ 280℃. Ninteguro ikomeye yo gutunganya ibinyampeke kandi ikora neza kugirango yongere yongere yongere yongererwe imbaraga kuri aluminiyumu, ifite ingaruka zigaragara kuri the imiterere nimiterere ya alloy kandi itezimbere cyane imbaraga zayo, ubukana, gusudira no kurwanya ruswa.

Scandium ifite ingaruka nziza zo gukwirakwiza kuri aluminium, kandi ikomeza imiterere ihamye idasubirwamo mubikorwa bishyushye cyangwa kuvura annealing. Amavuta amwe n'amwe ni impapuro zikonje zikonje hamwe na deforme nini, iracyakomeza iyi miterere na nyuma yo gufatana. Kubuza scandium kuri recrystallisation birashobora gukuraho imiterere ya recrystallisation muri zone yibasiwe nubushyuhe bwa weld, Imiterere ya subgrain ya matrix irashobora kwimurwa muburyo butaziguye bwo gusudira, bigatuma urugingo rusudira rwa aluminiyumu irimo scandium ifite imbaraga nyinshi no kurwanya ruswa.

Ingaruka za scandium ku kurwanya ruswa ya aluminiyumu nayo iterwa no gutunganya ingano no kubuza uburyo bwo kongera gukora.

Kwiyongera kwa scandium birashobora kandi gutuma aluminiyumu ya aluminiyumu igira superplasticity nziza, kandi kurambura aluminiyumu hamwe na 0.5% scandium irashobora kugera kuri 1100% nyuma yo kuvurwa bidasanzwe.

Kubera iyo mpamvu, Al-Sc alloy iteganijwe kuba igisekuru gishya cyibikoresho byoroheje byubatswe mu kirere, mu ndege no mu bwato, bikoreshwa cyane cyane mu gusudira imitwaro ibice bigize ikirere, indege n’ubwato, imiyoboro ya aluminiyumu yangiza ibidukikije byangiza, ibigega bya peteroli ya gari ya moshi, ibice byingenzi byubatswe bya gari ya moshi yihuta, nibindi

Icyifuzo cyo gusaba:

Sc-irimo aluminium aliyumu ifite ibyifuzo byinshi mubisabwa mu buhanga buhanitse nk'ubwato, inganda zo mu kirere, roketi na misile, ingufu za kirimbuzi, n'ibindi. ibikoresho bya aluminiyumu bishingiye ku mavuta ya aluminiyumu ariho, nka ultra-high strength hamwe na aluminiyumu ikomeye cyane, aluminiyumu ikomeye, irwanya imbaraga za aluminium, imbaraga za neutron irrasiyoyasi irwanya aluminiyumu n'ibindi.Iyi mavuta Bizagira ibyifuzo byiza cyane byo gukoresha mu kirere, ingufu za kirimbuzi n’inganda zubaka ubwato kubera ibintu byiza byuzuye, kandi birashobora no gukoreshwa mumodoka yoroheje na gari ya moshi yihuta. Kubwibyo, scandium irimo aluminiyumu yahindutse ikindi kintu gishimishije kandi gihatanira gukora cyane-aluminium alloy ibikoresho byubatswe nyuma ya AlLi alloy.Ubushinwa bukungahaye ku mutungo wa scandium kandi bufite umusingi runaka wubushakashatsi bwa scandium n’umusaruro ukomoka mu nganda, na nubu bikaba ari byoherezwa mu mahanga cyane okiside. Ni ingirakamaro mu bihe byogutezimbere ibikoresho bya aluminiyumu yubukorikori buhanitse n’ubwubatsi bw’igihugu mu Bushinwa, kandi irashobora AlSc guha uruhare runini ibyiza by’umutungo wa scandium mu Bushinwa kandi igateza imbere iterambere ry’inganda za scandium n’ubukungu bw’igihugu mu Bushinwa .
