Scandiumhe mea hoʻololi a ʻo kekahi o nā mea ʻeleʻele ʻeleʻele. Loaʻa iā ia nā waiwai maikaʻi e like me ka palupalu, nā waiwai kemika ikaika, ka conductivity kiʻekiʻe a me ka umekaumaha kikoʻī haʻahaʻa. Ke hoʻohui ʻia i nā alumini alumini, hiki iā ia ke hoʻomaikaʻi maikaʻi i ka ikaika, paʻakikī a me nā waiwai ʻē aʻe o nā alloys. He ʻano hou ia o ka trace element no ka hoʻomohala ʻana i nā alumini alumini ikaika kiʻekiʻe, kiʻekiʻe-wela-wela a kiʻekiʻe-corrosion. No ka mea he kiʻekiʻe loa ka helu heheʻe o ka scandium, ma 1541 ° C, ʻoiai ʻo ka helu heheʻe o ka alumini he 660 ° C wale nō, ʻokoʻa loa nā helu hoʻoheheʻe o nā metala ʻelua, no laila pono e hoʻohui ʻia ka scandium i ka alumini alumini ma ke ʻano o kahi hui waena. No laila, ʻo kaalumini-scandium hui waenaʻo ia ke kī kumu no ka hoʻomākaukau ʻana oaluminika-scandium alloys.
ʻO ka hoʻohui ʻana i ka nui o ka scandium (0.15 ~ 0.5wt%) i nā alumini alumini hiki ke pāʻani i kahi hana alloying maikaʻi. ʻO ka mea mua, hiki iā ia ke hoʻomaʻemaʻe nui i nā kīʻaha o nā mea hoʻoheheʻe ʻia a he mea hoʻomaʻemaʻe palaoa ikaika no nā alumini alumini. ʻO ka lua, hiki iā ia ke hoʻonui i ka mahana recrystallization e 250 ℃ ~ 280 ℃, e hoʻopau i ke ʻano recrystallized i loko o ka wahi wela o ka weld, a hiki i ke ʻano subgrained o ka matrix ke hoʻololi pololei i ke ʻano hoʻoheheʻe o ka weld e pale ai i ka wela wela a hoʻomaikaʻi i ke kūpaʻa haʻihaʻi luhi o ke alumini alumini. ʻO ia ka mea hoʻopaʻapaʻa recrystallization maikaʻi no nā alumini alumini a he hopena koʻikoʻi i ke ʻano a me nā waiwai o ka alloy, e hoʻomaikaʻi nui ana i kona ikaika, paʻakikī, modulus elastic, hana welding, pale wela, pale ʻana i ka corrosion a me ke kū'ē ʻana i ka pōʻino radiation neutron. I kēia manawa, ʻike ʻia ka ikaika oalumini-scandium huilahiki ke piʻi aku ma mua o 750MPa, a hiki i ka modulus elastic ma mua o 100GPa, ʻo ia ka 30% kiʻekiʻe ma mua o nā alumini alumini kuʻuna. ʻO ke kolu, hiki iā ia ke pāʻani i ka hana maikaʻi i ka hoʻoikaika ʻana i ka hoʻopuehu ʻana, e mālama ana i kahi ʻano paʻa ʻole-recrystallized i loko o ka mokuʻāina o ka hana wela a i ʻole ka hoʻomaʻamaʻa annealing, a loaʻa iā ia nā hiʻohiʻona o ka hana wela a me ke anu a me ke kūpaʻa wela kiʻekiʻe. ʻO ka hā, hiki iā ia ke hana i nā alumini alumini i ka superplasticity maikaʻi. Ma hope o ka hoʻomaʻamaʻa superplastic, hiki i ka elongation o nā alumini alumini me kahi 0.5% scandium i hoʻohui ʻia hiki ke hiki i 1100%.
Ma muli o nā ʻano mechanical maikaʻi loa o nā alumini alumini-scandium i ʻōlelo ʻia ma luna, e haki ana i ka bottleneck o ka ikaika alumini alumini kuʻuna, a me ka mālama ʻana i ka hana maikaʻi, ua hoʻomaka mālie nā huahana i hana ʻia i nā alumini alumini-scandium hou i nā mākeke o nā ʻāina holomua e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa. ʻO nā'āpana alumini-scandium kekahiʻano o ka hana kiʻekiʻe o ka alumini alumini hou me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kaumaha māmā. He mau mea kūpono ia no nā ʻāpana hoʻolālā mokulele, nā papa kaʻa, nā hui kolepa, a me nā mea ʻē aʻe. Hoʻohana nui ʻia lākou no ka hoʻopaʻa ʻana i nā ʻāpana o ka aerospace, aviation, a me nā moku, a me nā paipu alumini alumini no nā wahi media corrosive alkaline, nā pahu aila kaʻaahi, a me nā ʻāpana kumu nui o nā kaʻaahi kiʻekiʻe. Hoʻohana nui ʻia lākou i ka aerospace, ka lawe ʻana, ka ʻoihana nuklea, ka uila, nā pahu pahu, a me nā māla ʻē aʻe.
I kēia manawa, ʻoi aku ma mua o hoʻokahi tausani mau ʻano mea alumini alumini ma ka honua, i hana nui i ka holomua o ke kanaka. Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana a me ka hoʻomaikaʻi ʻana i nā kūlana ola, makemake nui koʻu ʻāina i ka hoʻomohala ʻana i nā alumini alumini kiʻekiʻe. ʻO ka hoʻomohala ʻana i nā mea haʻahaʻa scandium-aluminum intermediate alloys hiki ke kau i kahi kumu paʻa no ka hoʻomohala ʻana i kēia mau mea hana kiʻekiʻe, e hoʻoikaika nui i ka hoʻomohala ʻana o ka ʻoihana alumini a me ka ʻoihana scandium o koʻu ʻāina, a hoʻoikaika i ka hoʻohui ʻana o ka ʻoihana alumini o koʻu ʻāina me ka ʻoihana alumini honua. No laila, ʻo ka papahana hoʻomākaukau o ka aluminika-scandium (intermediate) alloy he mea nui a pono, a he kuhikuhi koʻikoʻi no ka hoʻomohala ʻana i nā mea alumini alumini i ka wā e hiki mai ana.
Hoʻomaʻamaʻa mākou i ka hāʻawi ʻana i ka Aluminum Scandium Alloy me ka hoʻokipa kiʻekiʻe kiʻekiʻekāhea iā mā˚oue loaa ke kumukuai
