ʻO nā'āpana titanium kiʻekiʻe a me ka hoʻokaʻawaleʻana a me nā waiwai o nāʻano likeʻole o ka titanium alloys!
ʻO ka titanium alloy kiʻekiʻe mua i hoʻomohala maikaʻi ʻia ma ka honua holoʻokoʻa ʻo Ti-6Al-4V, me kahi mahana lawelawe o 300-350 ℃. Ma hope iho, ua hoʻomohala ʻia nā ʻāpana e like me IMI550 a me BT3-1 me kahi mahana lawelawe o 400 ℃ a me IMI679, IMI685, Ti-6246, Ti-6242 me kahi mahana lawelawe o 450 ~ 500 ℃. Hou kiʻekiʻe-mehana titanium alloys i hoʻohana maikaʻi ʻia i nā ʻenekini mokulele e komo pū me IMI829 a me IMI834 alloys ma UK; Ti-1100 alloy ma ʻAmelika Hui Pū ʻIa; ʻO BT18Y a me BT36 nā mea hoʻohui i Rusia. I kēia mau makahiki i hala iho nei, ua hoʻohana nā ʻāina ʻē i ka ʻenehana paʻa paʻa / pauka metallurgy a me ka fiber a i ʻole nā mea i hoʻohui ʻia i hoʻohui ʻia e hoʻomohala i nā alloys titanium e like me ke kuhikuhi o ka hoʻomohala ʻana o nā alloys titanium kiʻekiʻe, i hiki ke hoʻonui ʻia ka mahana lawelawe o nā alloys titanium. i luna o 650 ℃. Ua hoʻomohala maikaʻi ʻo McDonnell Douglas o ʻAmelika Hui Pū ʻIa i kahi huila titanium maʻemaʻe kiʻekiʻe me ka hoʻohana ʻana i ka ʻenehana metallurgy paʻa wikiwiki. ʻO kona ikaika ma 760 ° C ua like ia me ka ikaika o nā alloys titanium i hoʻohana ʻia i kēia manawa ma ke ana wela.
ʻO nā huila Titanium e pili ana i nā pūhui titanium-aluminum
Ke hoʻohālikelikeʻia me nā'āpana titanium maʻamau,ʻo nā mea maikaʻi o nā pūhui titanium-aluminum e pili ana i ka sodium Ti3Al (α2) a me TiAl (γ) intermetallic pūhui he hana kiʻekiʻe kiʻekiʻe (ʻo ka mahana hana he 816 a me 982 ° C). maikaʻi kolo ke kū'ē, a me ka māmā kaumaha (density wale 1/2 o ka nickel-ma muli wela wela). ʻO kēia mau mea maikaʻi e lilo ia i mea hoʻokūkū no nā aero-engine a me nā ʻāpana hoʻolālā mokulele. I kēia manawa, ua hoʻomaka ʻelua mau huila titanium i hoʻokumu ʻia ʻo Ti3Al Ti-21Nb-14Al a me Ti-24Al-14Nb-#v-0.5Mo i ka hana nui ma United States. 'ē aʻe ʻO nā huila titanium ma muli o Ti3Al i kūkulu ʻia i nā makahiki i hala iho nei, ʻo ia ʻo Ti-24Al-11Nb, Ti25Al-17Nb-1Mo, a me Ti-25Al-10Nb-3V-1Mo. ʻO ka hui pū ʻana o nā ʻāpana titanium e pili ana iā TiAl (γ) ʻo TAl-(1-10) M (ma.%), kahi ʻo M ma kahi liʻiliʻi loa o v, Cr, Mn, Nb, Mn, Mo a me W. Ua hoʻomaka nā ʻāpana titanium i hoʻokumu ʻia ʻo TiAl3 e huki i ka nānā ʻana, e like me Ti-65Al-10Ni alloy.
ʻO ka ikaika kiʻekiʻe a me ka paʻakikī β-type titanium alloy
β-type titanium alloy ua hoʻomohala mua ʻia e Crucible ma ʻAmelika Hui Pū ʻIa i ka waena o 1950s e like me B120VCA alloy (Ti-13v-11Cr-3Al). ʻO ka β-type titanium alloy he mau mea wela a me ke anuanu maikaʻi, maʻalahi e paʻi, hiki ke ʻōwili ʻia a welded, a hiki ke loaʻa i nā waiwai mechanical kiʻekiʻe, ke kū ʻana o ke kaiapuni maikaʻi, a me ka hui maikaʻi ʻana o ka ikaika a me ka paʻakikī haʻihaʻi ma o ka hoʻoponopono ʻana i ka wā kahiko. . ʻO ka lunamakaʻāinana hou ka ikaika kiʻekiʻe a me ka paʻakikī β-type titanium alloys penei: Ti1023 (Ti-10v-2Fe-#al), ka mea i hana like me ka 30CrMnSiA kiʻekiʻe-ikaika structural kila i hoʻohana mau 'ia ma nā mokulele structural'āpana a me ka maikai forging hana; ʻO Ti153 (Ti-15V-3Cr-3Al-3Sn), ʻoi aku ka maikaʻi o ka hana maʻamau ma mua o ka titanium maʻemaʻe ʻoihana, a ʻo ka ikaika tensile wela o ka lumi ma hope o ka ʻelemakule hiki ke piʻi ma mua o 1000MPa; ʻO β21S (Ti-15Mo-3Al-2.7Nb-0.2Si), he ʻano hou ia o ka oxidation-resistant, ultra-high-strength titanium alloy i hoʻomohala ʻia e ka Timet division o ka hui metala titanium ʻAmelika, he maikaʻi ke kūpaʻa oxidation maikaʻi. maikaʻi loa ka hana hoʻoponopono wela a me ke anu, hiki ke hana ʻia i foil me ka mānoanoa o 0.064mm; SP-700 (Ti-4.5Al-3V-2Mo-2Fe) titanium alloy i hoʻomohala maikaʻi ʻia e Nippon Steel Tube Co., Ltd. (NKK) he ikaika kiʻekiʻe, superplastic elongation a hiki i 2000%, a me ka superplastic forming temperature he 140 ℃ haʻahaʻa ma mua o Ti-6Al-4V, hiki ke hoʻololi i ka alloy Ti-6Al-4V e hana i nā ʻāpana aerospace me ka hoʻohana ʻana i ka ʻenehana superplastic forming-diffusion bonding (SPF/DB); ʻO BT-22 (TI-5v-5Mo-1Cr-5Al) i hoʻomohala ʻia e Rūsia he ikaika tensile ʻoi aku ma mua o 1105MPA.
ʻAi ʻia ʻo titanium pale ahi
Hoʻopau nā mea hoʻoheheʻe titanium maʻamau i nā alkanes ma lalo o kekahi mau kūlana, kahi e kaupalena nui ai i kā lākou noi. I ka pane ʻana i kēia kūlana, ua hoʻomaka nā ʻāina like ʻole i ka noiʻi e pili ana i nā aloi titanium flame-retardant a loaʻa i kekahi mau holomua. ʻO Alloy C (ʻike pū ʻia ʻo T) i hoʻomohala ʻia e Qiang State he 50Ti-35v-15Cr (kahi hapa nui). ʻO ia ke ahi-retardant titanium alloy ʻaʻole i ʻike i ka hoʻomau mau ʻana a ua hoʻohana ʻia i nā mīkini F119. ʻO ka BTT-1 a me ka BTT-3 he mau ʻāpana titanium pale ahi i hoʻomohala ʻia e Rūsia. ʻO nā mea ʻelua ʻo Ti-Cu-Al alloys me ka maikaʻi loa o ke kaʻina hana deformation thermal a hiki ke hoʻohana ʻia e hana i nā ʻāpana paʻakikī.
Nā lāʻau lapaʻau titanium
ʻAʻole ʻona ka Titanium, māmā, kiʻekiʻe i ka ikaika, a he biocompatibility maikaʻi loa. He mea metala lāʻau lapaʻau kūpono a hiki ke hoʻohana ʻia ma ke ʻano he implant no ke kino kanaka. I kēia manawa, hoʻohana nui ʻia ʻo Ti-6Al-4v i ka lāʻau lapaʻau. ELI huila. Eia nō naʻe, ʻo ka mea hope e hoʻoheheʻe i kahi liʻiliʻi loa o ka vanadium a me nā ion alumini, e hōʻemi ana i kona hiki ke hoʻololi i ke kelepona a hiki ke hōʻeha i ke kino o ke kanaka. Ua lōʻihi kēia pilikia i ka manaʻo nui i ke kaiāulu olakino. I ka hoʻomaka ʻana o ka waena o 1980s, ua hoʻomaka ʻo ʻAmelika e hoʻomohala i ka alumini-free, vanadium-free, biocompatible titanium alloys no ka hoʻohana ʻana i nā orthopedics. Ua hana ʻo Iapana, United Kingdom, a me nā ʻāina ʻē aʻe i ka noiʻi nui ma kēia wahi a ua holomua hou. No ka laʻana, ua hoʻomohala ʻo Iapana i kahi pūʻulu o α+β titanium alloys me ka biocompatibility maikaʻi loa, me Ti-15Zr-4Nb_4ta-0.2Pd, Ti-15Zr-4Nb-aTa-0.2Pd-0.20~0.05N, Ti-15Sn-4Nb- 2Ta-0.2Pd a me Ti-15Sn-4nb-2Ta-0.2Pd-0.20. ʻOi aku ka maikaʻi o ka ikaika o ka corrosion, ka luhi luhi, a me ka pale ʻana i ka corrosion o kēia mau ʻāpana ma mua o ka Ti-6Al-4v ELI. Ke hoʻohālikelike ʻia me ka α + β titanium alloy, ʻoi aku ka ikaika o ka β titanium alloy, ʻoi aku ka maikaʻi o ka ʻoki ʻana, a me ka paʻakikī, a ʻoi aku ka maikaʻi no ka hoʻokomo ʻana i ke kino kanaka. Ma ʻAmelika Hui Pū ʻIa, ʻelima β titanium alloys ua paipai ʻia no ke kahua lapaʻau, ʻo ia hoʻi ʻo TMZFTM (TI-12Mo-^Zr-2Fe), Ti-13Nb-13Zr, Timetal 21SRx (TI-15Mo-2.5Nb-0.2Si), Tiadyne 1610 (Ti-16Nb-9.5Hf ) a me Ti-15Mo. Ua manaʻo ʻia ʻaʻole hiki ke hoʻololi i kēia ʻano huila titanium me ka ikaika kiʻekiʻe, modulus elastic haʻahaʻa, formability maikaʻi loa, a me ka pale ʻana i ka corrosion e hoʻololi i ka huila Ti-6Al-4V ELI i kēia manawa i hoʻohana nui ʻia i ka lāʻau lapaʻau.
