Aluminum alloy no ka pahu wahie rocket
Pili nā mea kūkulu hale i nā ʻano pilikia e like me ka hoʻolālā ʻana i ke kino rocket, ka hana ʻana a me ka ʻenehana hana, ka ʻenehana hoʻomākaukau waiwai, a me ka hoʻokele waiwai, a ʻo ia ke kī i ka hoʻoholo ʻana i ka maikaʻi o ka lawe ʻana a me ka hiki ke uku. Wahi a ke kaʻina hana hoʻomohala o ka ʻōnaehana waiwai, hiki ke hoʻokaʻawale ʻia ke kaʻina hana hoʻomohala o nā mea pahu pahu pahu rocket i ʻehā mau hanauna. ʻO ka hanauna mua he 5-series aluminum alloys, ʻo ia hoʻi, Al-Mg alloys. ʻO nā huila ʻelele he 5A06 a me 5A03 alloys. Ua hoʻohana ʻia lākou no ka hana ʻana i nā hale pahu wahie rocket P-2 i ka hopena o nā makahiki 1950 a hoʻohana mau ʻia i kēia lā. ʻO 5A06 nā alapili i loaʻa ka 5.8% Mg a hiki i ka 6.8% Mg, 5A03 kahi huila Al-Mg-Mn-Si. ʻO ka lua o ka hanauna he Al-Cu-based 2-series alloys. Hana ʻia nā pahu hoʻopaʻa o nā kaʻa hoʻokuʻu ʻia ʻo Long March o Kina me 2A14 alloys, ʻo ia ka Al-Cu-Mg-Mn-Si alloy. mai ka 1970s a hiki i kēia manawa, ua hoʻomaka ʻo Kina e hoʻohana i ka pahu waihona pahu hana hao hao 2219, ʻo ia ka Al-Cu-Mn-V-Zr-Ti alloy, i hoʻohana nui ʻia i ka hana ʻana i nā pahu mālama kaʻa hoʻomaka. I ka manawa like, hoʻohana nui ʻia ia i ke ʻano o nā mea kaua e hoʻomaka ai i nā pahu wahie haʻahaʻa haʻahaʻa, ʻo ia ka alloy me ka hana haʻahaʻa haʻahaʻa maikaʻi loa a me ka hana piha.
Aluminum alloy no ka hale hale
Mai ka hoʻomohala ʻana o nā kaʻa hoʻokuʻu ʻia ma Kina i ka makahiki 1960 a hiki i kēia manawa, ʻo nā alumini alumini no ka hale kaʻa o nā kaʻa hoʻokuʻu ʻia e noho aliʻi ʻia e ka hanauna mua a me ka lua o ka lua o nā alloys i hōʻike ʻia e 2A12 a me 7A09, ʻoiai ua komo nā ʻāina ʻē i ka hā o ka hanauna. cabin structural aluminum alloys (7055 alloy a me 7085 alloy), ua hoʻohana nui ʻia lākou ma muli o ko lākou ikaika kiʻekiʻe, haʻahaʻa quenching sensitivity. a me ka notch sensitivity. ʻO 7055 kahi huila Al-Zn-Mg-Cu-Zr, a ʻo 7085 kahi huila Al-Zn-Mg-Cu-Zr, akā haʻahaʻa loa kona kino Fe a me Si, a kiʻekiʻe ka Zn ma 7.0% ~8.0%. ʻO ke kolu o ka hanauna Al-Li alloys i hōʻike ʻia e 2A97, 1460, a me nā mea ʻē aʻe i hoʻohana ʻia i nā ʻoihana aerospace haole ma muli o ko lākou ikaika kiʻekiʻe, modulus kiʻekiʻe, a me ka elongation kiʻekiʻe.
Loaʻa i nā mea hoʻohui alumini matrix i hoʻoikaika ʻia i nā mea maikaʻi o ka modulus kiʻekiʻe a me ka ikaika kiʻekiʻe, a hiki ke hoʻohana ʻia e hoʻololi i nā alloys 7A09 e hana i nā stringers cabin semi-monocoque. Ua hana nui ka Institute of Metal Research, Chinese Academy of Sciences, Harbin Institute of Technology, Shanghai Jiaotong University, etc.
Al-Li alloys i hoʻohana ʻia i nā aerospace haole
ʻO ka noi kūleʻa loa ma nā kaʻa aerospace haole ʻo ia ka Weldalite Al-Li alloy i hoʻomohala ʻia e Constellium a me Quebec RDC, me 2195, 2196, 2098, 2198, a me 2050 Alloy. 2195 alloy: Al-4.0Cu-1.0Li-0.4Mg-0.4Ag-0.1Zr, ʻo ia ka Al-Li alloy mua i kūleʻa maikaʻi ʻia no ka hana ʻana i nā pahu waiho wahie haʻahaʻa haʻahaʻa no ka hoʻokuʻu ʻana. 2196 huila: Al-2.8Cu-1.6Li-0.4Mg-0.4Ag-0.1Zr, haʻahaʻa haʻahaʻa, ikaika kiʻekiʻe, kiʻekiʻe haʻi paʻakikī, i hoʻomohala mua ʻia no nā kiʻi kiʻi kiʻi solar panel Hubble, i kēia manawa ua hoʻohana nui ʻia no ka extruding profiles mokulele. 2098 alloy: Al-3.5 Cu-1.1Li-0.4Mg-0.4Ag-0.1Zr, i hoʻokumu mua ʻia no ka hana ʻana i ka fuselage HSCT, no kona ikaika luhi kiʻekiʻe, ua hoʻohana ʻia ia i ka fuselage F16 fighter a me ka mokulele Falcon hoʻokuʻu wahie pahu. . 2198 alloy: Al-3.2Cu-0.9Li-0.4Mg-0.4Ag-0.1Zr, hoʻohana ʻia no ka ʻōwili pepa mokulele mokulele. 2050 alloy: Al-3.5Cu-1.0Li-0.4Mg- 0.4Ag-0.4Mn-0.1Zr, hoʻohana ʻia e hana i nā papa mānoanoa e pani i nā papa mānoanoa 7050-T7451 no ka hana ʻana i nā hale mokulele mokulele a i ʻole nā mea hoʻokuʻu rocket. Ke hoʻohālikelike ʻia me ka 2195 alloy, ʻo ka Cu + Mn content o ka 2050 alloy he haʻahaʻa haʻahaʻa e hōʻemi i ka naʻau hoʻopau a mālama i nā waiwai mechanical kiʻekiʻe o ka pā mānoanoa, ʻo ka ikaika kikoʻī he 4% kiʻekiʻe, ʻo ka modulus kikoʻī he 9% kiʻekiʻe, a hoʻonui ʻia ka paʻakikī o ka haʻihaʻi me ke koʻikoʻi kiʻekiʻe o ka corrosion cracking resistance a me ka ulu ʻana o ka ulu ʻana o ka luhi luhi, a me ke kūpaʻa wela kiʻekiʻe.
ʻO ka noiʻi ʻana a Kina e pili ana i ka hoʻopaʻa ʻana i nā apo i hoʻohana ʻia i nā hale pōhaku
Aia ke kahua hana kaʻa hoʻomaka o Kina ma ka Tianjin Economic and Technological Development Zone. Hoʻokumu ʻia ia me kahi wahi noiʻi rocket a me kahi wahi hana, kahi ʻoihana noi ʻenehana aerospace a me kahi wahi kākoʻo kōkua. Hoʻohui ia i ka hana ʻāpana rocket, hui ʻāpana, hoʻāʻo ʻana i ka hui hope.
Hoʻokumu ʻia ka pahu hoʻopaʻa rocket propellant e ka hoʻopili ʻana i nā cylinders me ka lōʻihi o 2m a 5m. Hana ʻia nā pahu mālama i ka alumini alumini, no laila pono lākou e hoʻopili ʻia a hoʻoikaika ʻia me nā apo alumini alumini. Eia kekahi, pono e hoʻohana nā mea hoʻohui, nā apo hoʻololi, nā papa hoʻololi a me nā ʻāpana ʻē aʻe o ka mokulele e like me nā kaʻa hoʻokuʻu a me nā kikowaena kikowaena e hoʻohana i nā apo forging hoʻohui, no laila he ʻano koʻikoʻi loa nā apo forging o ka hoʻohui ʻana a me nā ʻāpana kūkulu. Southwest Aluminum (Group) Co., Ltd., Northeast Light Alloy Co., Ltd., a me Northwest Aluminum Co., Ltd. i hana nui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana a me ka hana ʻana i nā apo forging.
I ka makahiki 2007, ua lanakila ʻo Southwest Aluminum i nā pilikia ʻenehana e like me ka hoʻolei ʻana i ka nui, ka wehe ʻana i ka billet, ka ʻōwili ʻana o ke apo, a me ka deformation anu, a ua hoʻomohala i kahi apo alumini forging apo me ke anawaena o 5m. ʻO ka ʻenehana forging kumu kumu i hoʻopiha i ka hakahaka o ka home a ua hoʻohana maikaʻi ʻia i Long March-5B. I ka makahiki 2015, ua hoʻokumu ʻo Southwest Aluminum i ke apo alumini nui nui loa me ke anawaena o 9m, e hoʻokumu ana i kahi moʻolelo honua. I ka makahiki 2016, lanakila lanakila ʻo Southwest Aluminum i kekahi mau ʻenehana koʻikoʻi nui e like me ka rolling forming a me ka mālama ʻana i ka wela, a ua hoʻomohala i kahi apo alumini nui nui me ke anawaena o 10m, i hoʻonohonoho i kahi moʻolelo honua hou a hoʻoponopono i kahi pilikia ʻenehana nui. no ka hoʻomohala ʻana i ke kaʻa hoʻokele kaumaha o Kina.
Hoʻoponopono ʻia e May Jiang mai MAT Aluminum
