Electron beam hehee 3D paʻi ʻana i ka titanium alumini ʻāpana paʻakikī
Loaʻa nā ʻano o ka alloy TiAl i ka haʻahaʻa haʻahaʻa, ka ikaika kikoʻī kiʻekiʻe, ka modulus kiʻekiʻe, ke kūpaʻa ʻana o ka oxidation kiʻekiʻe, a me nā mea ʻē aʻe, ma kahi o 50% ka māmā ma mua o ka nickel based superalloy.
Electron beam hehee metalaPaʻi 3Dʻenehana no ka hoʻomākaukau ʻana i nā mea hoʻoheheʻe ʻia ʻo TiAl ma ke ʻano he ʻano hana hou a ʻoi loa, ua manaʻo ʻia ʻo ia ke koho maikaʻi loa no ka hoʻokumu ʻana i nā mea hoʻoheheʻe ʻia ʻo TiAl, a me kāna micro-zone melting, hoʻōla wela, hoʻopaʻa wikiwiki a me nā pono ʻenehana ʻē aʻe. Hoʻopau ʻia nā pilikia o ka hoʻolālā koʻikoʻi a me ka paʻa paʻa paʻa ʻole i ka hoʻolei ʻana, ka metallurgy ingot a me ka metallurgy pauka. Ma muli o kona mau hiʻohiʻona ponoʻī, lawe mai ia i nā pilikia ʻenehana nui i ke kaʻina hana uila electron.
I Malaki 2021, ua hāʻule nā pilikia ʻenehana e like me ka pauka (puhi ʻana i ka pauka), lawa ʻole ka pilina interlayer, volatilization oaluminika, haʻahaʻa haʻahaʻa, uneven transverse a me ka longitudinal hale waiwai o nā ʻāpana i hoʻoholo ʻia i ke kaʻina hana o ka kukuna electron e hana ana i ka alloy TiAl.
ʻO ka hoʻonui ʻana a me ka hoʻomaikaʻi ʻana i nā ʻāpana kaʻina hana no ka hoʻomākaukau ʻana i nā ʻāpana paʻakikī nui e ka electron beam melting 3d printer ʻenehana, ka hoʻoponopono ʻana i ka microstructure evolution o nā mea ma nā kiʻekiʻe kiʻekiʻe, a me ka hoʻololi ʻana i nā kaʻina hana a me nā kūlana paʻi, ʻo ka Ø110mm × 66mm nui loa a me ka māwae ʻole ʻo Ti-48Al-2Cr-2Nb i kūleʻa maikaʻi loa. Ua hana ʻia nā mea hou i ka titanium a me nā ʻāpana paʻakikī alumini. Ma ka manawa like, ma ka hoʻopololei ʻana i ke ala scanning a me ka nānā ʻana i ka beam spot, ua lanakila ke kaʻina hana o nā ʻāpana hoʻololi curved ʻoi aku ka paia.
Poha koke ka pauda kaola uila
Ma o ka hoʻomaikaʻi ʻana a me ka hoʻomaikaʻi ʻana i ke kaʻina hana preheating, ua paʻi maikaʻi ʻia ke koʻokoʻo hoʻāʻo nui me ka hana like ma nā kiʻekiʻe like ʻole.

Ma hope o ka hoʻoponopono ʻana i ka ʻiʻo hope, ʻoi aku ka lōʻihi o ka transverse a me ka longitudinal microstructure o ka Ti-48Al-2Cr-2Nb specimen, a hiki ke piʻi aku ka nui ma mua o 99.6%. Hōʻike ka papa ma lalo nei i ka awelika o nā waiwai mechanical o ka pahu hoʻāʻo transverse a longitudinal.

| Ka wela lumi | ≥430 | ≥510 | ≥1.8 |
Nā waiwai mīkini o ka pauka Ti-48Al-2Cr-2Nb i pai ʻia e ka ʻenehana beam electron

Ua hōʻike ʻia ua hoʻolaha ʻo GE Aviation ua hōʻoia ʻia ka ʻenekini GE9XFAA e ka Federal Aviation Administration (FAA), a ʻoi aku ka nui o ka mīkini ma mua o 300 mau ʻāpana hana hoʻohui, kahi o ka titanium alumini haʻahaʻa turbine puʻupuʻu i hana ʻia e ka electron beam selective melting technology kekahi o lākou.
