He aha ka metala i hana ʻia me ka titanium alloy?
I ka wā ma mua, nui nā mea kūʻai aku i nīnau i kā mākou nā mea hana pahu pahu titanium alloy kekahi mau nīnau e pili ana i nā pahu hao titanium. I kēia manawa e pili ana i ka nīnau o ka mea i hana ʻia ai nā ʻāpana titanium metala, makemake wau e hōʻuluʻulu i nā ʻōlelo aʻe no ʻoe, me ka manaʻo e kōkua i nā mea āpau.
He aha ka metala i hana ʻia me ka titanium alloy?
ʻO ka alloy Titanium kahi huila e pili ana i ka titanium a hoʻohui ʻia me nā mea ʻē aʻe.
ʻO Titanium kahi aniani isomorphous me kahi helu heheʻe o 1720°C. Loaʻa iā ia kahi hoʻolālā hexagonal lattice kokoke loa ma lalo o 882 ° C, i kapa ʻia ʻo alpha titanium; loaʻa iā ia kahi hoʻolālā cubic lattice e pili ana i ke kino ma luna o 882 ° C, i kapa ʻia ʻo beta titanium. Ma ka hoʻohana ʻana i nā hiʻohiʻona like ʻole o nā hale ʻelua o ka titanium, a me ka hoʻohui ʻana i nā mea hoʻohui kūpono e hoʻololi mālie i ka mahana o ka hoʻololi ʻana o ka pae a me ka ʻike o ka pae, loaʻa nā alloys titanium me nā ʻano like ʻole. Ma ka lumi wela, ua loaʻa i nā alloys titanium ʻekolu mau hale matrix, a nā mea hana pahu pahu titanium alloy ua māhele ʻia i ʻekolu mau ʻāpana: α alloy, (α+β) alloy, a me β alloy. I koʻu ʻāina, hōʻike ʻia lākou e TA, TC, a me TB.
α titanium huila
ʻO ia kahi huila hoʻokahi-phase i haku ʻia me ka solution solid α-phase. ʻO ia ka α-phase inā ma nā mahana maʻamau a ʻoi aku paha nā mahana hoʻohana maoli. Loaʻa iā ia kahi ʻano paʻa, ʻoi aku ke kūpaʻa o ka lole ma mua o ka titanium maʻemaʻe, a me ke kūpaʻa oxidation ikaika. Ma nā mahana o 500 ° C a hiki i 600 ° C, mālama mau ia i kona ikaika a me ke kū'ēʻana, akā,ʻaʻole hiki ke hoʻoikaikaʻia e ka wela wela aʻaʻole kiʻekiʻe ka ikaika o ka mahana wela.
β titanium huila
ʻO ia kahi huila hoʻokahi-phase i haku ʻia me ka solution solid β-phase. Loaʻa ka ikaika kiʻekiʻe me ka mālama ʻole ʻana i ka wela. Ma hope o ke kinai ʻana a me ka ʻelemakule, ua hoʻoikaika hou ʻia ka alloy, a hiki i ka ikaika wela o ka lumi ke hiki i 1372 ~ 1666 MPa; akā naʻe, ʻaʻole pono ke hoʻohana ʻia i nā wela kiʻekiʻe.
α+β titanium huila
ʻO ia kahi hui lua-phase me nā waiwai piha maikaʻi, paʻa paʻa maikaʻi, paʻakikī maikaʻi, plasticity, a me nā waiwai deformation kiʻekiʻe. Hiki ke hoʻomaʻamaʻa maikaʻi ʻia e ka puʻe wela a hiki ke kinai ʻia a ʻelemakule e hoʻoikaika ai i ka alloy. ʻO ka ikaika ma hope o ka mālama ʻana i ka wela ma kahi o 50% a 100% kiʻekiʻe ma mua o ka mokuʻāina annealed; loaʻa iā ia ka ikaika wela kiʻekiʻe a hiki ke hana ma nā mahana o 400 ° C a 500 ° C no ka manawa lōʻihi. ʻOi aku ka haʻahaʻa o kona kūpaʻa wela i ka α titanium alloy.
Ma waena o nā'āpana titaniumʻekolu, hoʻohana mauʻia ka α titanium alloy a me ka α + β titanium alloy; Loaʻa i ka α titanium alloy ka machinability maikaʻi loa, a ukali ʻia e α+p titanium alloy, a ʻoi aku ka ʻino o ka β titanium alloy. Hoʻopili ʻia ka alpha titanium alloy e like me TA, ua helu ʻia ka beta titanium alloy e like me TB, a ua helu ʻia ka alpha + beta titanium alloy e like me TC.
Hiki ke hoʻokaʻawaleʻia nā'āpana Titanium i nā'āpana wela, nā'āpana ikaika kiʻekiʻe, nā'āpana pale pale (titanium-molybdenum, titanium-palladium alloys, a me nā mea'ē aʻe). a me nā mea hoʻomanaʻo hoʻomanaʻo titanium-nickel) e like me kā lākou hoʻohana.
Hoʻomaʻamaʻa wela: Hiki i nā huila Titanium ke loaʻa i nā haku mele a me nā hale like ʻole ma o ka hoʻoponopono ʻana i ke kaʻina hana wela. Manaʻo nui ʻia ʻo ke ʻano equiaxed maikaʻi he plasticity maikaʻi, kūpaʻa wela, a me ka ikaika luhi; ʻO ka ʻōnaehana acicular ka ikaika mau loa, ka ikaika kolo, a me ka paʻakikī haʻihaʻi; ʻO ka equiaxed a me ka acicular mixed structure he mau hana piha maikaʻi.
I ka hōʻuluʻulu ʻana, ʻo nā mea a pau i luna nā mea hana pahu pahu titanium alloy ua pane aku iā ʻoe. Inā loaʻa iā ʻoe kekahi koi no nā huahana pili, ʻoluʻolu ʻoe e kau i kahi kauoha.
