A hiki i kēia manawa, ua lilo ka microalloying i ka hoʻolālā hoʻomohala ʻenehana maikaʻi loa no ka hoʻonui ʻana i ka microstructure o nā alumini alumini a me ka hoʻomaikaʻi ʻana i nā waiwai piha o nā mea alumini alumini.Scandium(Sc) ʻo ia ka mea hoʻonui microalloying element maikaʻi loa i ʻike ʻia no nā alumini alumini. ʻO ka solubility o ka scandium i loko o ka alumini matrix ʻoi aku ka liʻiliʻi ma mua o 0.35 wt.%, ʻo ka hoʻohui ʻana i ka nui o ka scandium element i nā alumini alumini hiki ke hoʻomaikaʻi maikaʻi i kā lākou microstructure, hoʻonui piha i ko lākou ikaika, paʻakikī, plasticity, thermal stability, a me ka corrosion resistance. He nui nā hopena kino o Scandium i nā alumini alumini, me ka hoʻoikaika ʻana i ka hopena paʻa, ka hoʻoikaika ʻana i ka ʻāpana, a me ka pale ʻana i ka recrystallization. E hōʻike ana kēia ʻatikala i ka hoʻomohala mōʻaukala, ka holomua hou loa, a me nā noi kūpono o ka scandium i loaʻa nā alumini alumini ma ke kahua o ka hana ʻana i nā lako mokulele.
Noiʻi a hoʻomohala ʻana i ka Aluminum Scandium Alloy
Hiki ke huli ʻia ka hoʻohui ʻana o scandium ma ke ʻano he mea hoʻohui i nā alumini alumini i nā makahiki 1960. I kēlā manawa, ua lawe ʻia ka hapa nui o ka hana ma nā ʻōnaehana Al Sc binary a me nā ʻōnaehana alloy AlMg Sc ternary. I ka makahiki 1970, ua alakaʻi ka Baykov Institute of Metallurgy and Materials Science o ka Soviet Academy of Science a me ka All Russian Institute of Light Alloy Research i kahi noiʻi ʻōnaehana ma ke ʻano a me ke ʻano o ka scandium i nā alumini alumini. Ma hope o nā makahiki he kanahā o ka hoʻoikaika ʻana, ua hoʻomohala ʻia nā māka 14 o nā alumini scandium alloys i ʻekolu pūʻulu nui (Al Mg Sc, Al Li Sc, Al Zn Mg Sc). He haʻahaʻa ka solubility o nā ʻātoma scandium i loko o ka alumini, a ma ka hoʻohana ʻana i nā kaʻina mālama wela kūpono, hiki ke hoʻoheheʻe ʻia nā kiʻekiʻe Al3Sc nano precipitates. Kokoke spherical kēia pae ua, me nā ʻāpana liʻiliʻi a me ka hoʻopuehu ʻana, a he pilina pili maikaʻi me ka matrix aluminika, hiki ke hoʻomaikaʻi nui i ka ikaika wela o ka lumi o nā alumini alumini. Eia kekahi, ʻo Al3Sc nano precipitates he kūpaʻa wela maikaʻi a me ke kūpaʻa coarsening i nā wela kiʻekiʻe (i loko o 400 ℃), he mea maikaʻi loa ia no ke kūpaʻa wela ikaika o ka alloy. Ma Lūkia i hana ʻia nā alumini scandium alloys, 1570 alloy ua hoʻokipa nui ʻia ma muli o kona ikaika kiʻekiʻe a me kāna noi ākea. Ke hōʻike nei kēia huila i ka hana maikaʻi loa ma ka pae wela hana o -196 ℃ a 70 ℃ a he superplasticity kūlohelohe, hiki ke pani i ka LF6 alumini alumini i hana ʻia e Lūkia (he alumini magnesium alumini ka mea nui i haku ʻia me ka aluminika, magnesium, keleawe, manganese, a me ke silika) no nā hale kuʻi ʻana i ka ukana i loko o ka wai oxygen medium, me ka hoʻomaikaʻi maikaʻi ʻana i ka hana. Eia kekahi, ua hoʻomohala ʻo Rūsia i nā alumini zinc magnesium scandium alloys, i hōʻike ʻia e 1970, me ka ikaika waiwai ma luna o 500MPa.
Ke Kūlana Hana Hana oAluminum Scandium Alloy
Ma 2015, ua hoʻokuʻu ka European Union i ka "European Metallurgical Roadmap: Prospects for Manufacturers and End Users", e noi ana e aʻo i ka weldability o ka alumini.nā ʻāpana magnesium scandium. I Kepakemapa 2020, ua hoʻokuʻu ka European Union i kahi papa inoa o 29 mau kumu waiwai koʻikoʻi, me ka scandium. ʻO ka 5024H116 alumini magnesium scandium alloy i hoʻomohala ʻia e Ale Aluminum ma Kelemānia he ʻano ikaika a me ke kiʻekiʻe kiʻekiʻe a me ka hoʻomanawanui pōʻino, e lilo ia i mea hoʻohiki maikaʻi loa no ka ʻili fuselage. Hiki ke hoʻohana ʻia e hoʻololi i nā alumini alumini kuʻuna 2xxx series a ua hoʻokomo ʻia i loko o ka puke kūʻai mea waiwai Airbus 'AIMS03-01-055. ʻO 5028 kahi papa i hoʻomaikaʻi ʻia o 5024, kūpono no ka welding laser a me ka friction stir welding. Hiki iā ia ke hoʻokō i ke kaʻina hana creep o ka hyperbolic integral wall panels, ʻo ia ka corrosion-resistant a ʻaʻole koi i ka uhi alumini. Hoʻohālikelike ʻia me 2524 alloy, hiki ke hoʻemi ʻia ke kaumaha o ke kino o ka pā o ka fuselage i ka 5%. Ua hoʻohana ʻia ka AA5024-H116 aluminum scandium alloy sheet i hana ʻia e Aili Aluminum Company no ka hana ʻana i nā fuselage mokulele a me nā mea hoʻolālā mokulele. ʻO ka mānoanoa maʻamau o ka pepa AA5024-H116 he 1.6mm a hiki i ka 8.0mm, a ma muli o kona haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa mechanical, kiʻekiʻe corrosion kūpaʻa, a me ke koʻikoʻi deviation dimensional, hiki iā ia ke pani i ka 2524 alloy e like me ka fuselage ʻili mea. I kēia manawa, ua hōʻoia ʻia ka pepa alloy AA5024-H116 e Airbus AIMS03-04-055. I Kekemapa 2018, ua hoʻokuʻu ka Ministry of Industry and Information Technology o Kina i ka "Guiding Catalog for the First Batch of Secondary Application Demonstrations of Key New Materials (2018 Edition)", i komo pū me "high-purity scandium oxide" i ka papa kuhikuhi hoʻomohala o ka ʻoihana waiwai hou. I ka makahiki 2019, ua hoʻokuʻu ka Ministry of Industry and Information Technology o Kina i ka "Guiding Catalog for the First Batch of Demonstration Applications of Key New Materials (2019 Edition)", i komo pū me "Sc i loaʻa i nā mea hoʻoheheʻe alumini alumini a me Al Si Sc welding wires" i ka palapala hoʻomohala o ka ʻoihana waiwai hou. Ua kūkulu ʻo China Aluminum Group Northeast Light Alloy i kahi Al Mg Sc Zr series 5B70 alloy i loaʻa ka scandium a me ka zirconium. Ke hoʻohālikelike ʻia me ka Al Mg series 5083 alloy me ka scandium a me ka zirconium, ua hoʻonui ʻia kona hua a me ka ikaika tensile ma mua o 30%. Eia kekahi, hiki i ka Al Mg Sc Zr alloy ke mālama i ka pale ʻana i ka corrosion e like me ka 5083 alloy. I kēia manawa, ʻo nā ʻoihana kūloko nui me ka pae ʻoihanaalumina scandium alloyʻO ka mana hana ʻo Northeast Light Alloy Company a me Southwest Aluminum Industry. ʻO ka 5B70 aluminum scandium alloy sheet nui i hoʻomohala ʻia e Northeast Light Alloy Co., Ltd. hiki ke hāʻawi i nā papa mānoanoa alumini nui me ka mānoanoa o 70mm a me ka laulā kiʻekiʻe o 3500mm; Hiki ke hoʻopilikino ʻia nā huahana pepa lahilahi a me nā huahana profile no ka hana ʻana, me ka mānoanoa o 2mm a 6mm a me ka laulā kiʻekiʻe o 1500mm. Ua hoʻomohala kūʻokoʻa ʻo Southwest Aluminum i nā mea 5K40 a ua holomua nui i ka hoʻomohala ʻana i nā papa lahilahi. ʻO ka Al Zn Mg alloy he manawa paʻakikī paʻakikī me ka ikaika kiʻekiʻe, ka hana hoʻoponopono maikaʻi, a me ka hana hoʻoheheʻe maikaʻi. He mea koʻikoʻi a koʻikoʻi i nā kaʻa kaʻa e like me nā mokulele. Ma ke kumu o ka ikaika waena weldable AlZn Mg, hoʻohui i ka scandium a me ka zirconium alloy element hiki ke hana i nā nanoparticles Al3 (Sc, Zr) liʻiliʻi a hoʻopuehu i loko o ka microstructure, me ka hoʻomaikaʻi nui ʻana i nā waiwai mechanical a me ke koʻikoʻi ke kūpaʻa corrosion o ka alloy. Ua hoʻomohala ʻo Langley Research Center o NASA i kahi alumini alumini scandium alloy me ka papa C557, i mākaukau e hoʻohana ʻia i nā mikiona kumu. ʻO ka ikaika paʻa, ka hoʻolaha ʻana o ka māwae, a me ka paʻakikī o ka haʻihaʻi ʻana o kēia huila i ka wela haʻahaʻa (-200 ℃), ka wela o ka lumi, a me ka wela kiʻekiʻe (107 ℃) ua like a ʻoi aku ka maikaʻi ma mua o ka 2524 alloy. Ua hoʻomohala ʻo Northwestern University ma ʻAmelika Hui Pū ʻIa i ka AlZn Mg Sc alloy 7000 series ultra-high strength aluminum alloy, me ka ikaika tensile a hiki i 680MPa. Ua hoʻokumu ʻia kahi ʻano o ka hoʻomohala ʻana ma waena o ka alumini scandium alloy kiʻekiʻe kiʻekiʻe a me ka ikaika ultra-kiʻekiʻe Al Zn Mg Sc. ʻO Al Zn Mg Cu Sc alloy he alumini alumini ikaika kiʻekiʻe me ka ikaika tensile ma mua o 800 MPa.
