Beam ea elektrone e qhibilihisa likarolo tsa meralo tse rarahaneng tsa 3D tsa titanium aluminium
Alloy e thehiloeng ho TiAl e na le litšobotsi tsa boima bo tlase, matla a khethehileng a phahameng, modulus e phahameng, ho hanyetsa mocheso o phahameng oa oxidation, joalo-joalo, e ka bang 50% e bobebe ho feta superalloy e thehiloeng ho nickel.
tšepe e qhibilihang ka tšepe ea elektroneKhatiso ea 3Dthekenoloji bakeng sa ho lokisoa ha lisebelisoa tsa alloy tse thehiloeng ho TiAl e le mokhoa o mocha le o tsoetseng pele ka ho fetisisa oa ho theha, o nkoa e le khetho e ntle ka ho fetisisa ea ho etsa lisebelisoa tsa alloy tse thehiloeng ho TiAl, le ho qhibiliha ha eona ho ikhethang ha micro-zone, phekolo ea mocheso oa potoloho, ho tiisa ka potlako le melemo e meng ea theknoloji. Mathata a sebopeho se mahoashe le sebopeho se hlephileng sa ho tiisa ho lahla, metallurgy ea ingot le metallurgy ea phofo ea hlōloa. Ka lebaka la litšoaneleho tsa eona, e tlisa mathata a maholo a tekheniki ts'ebetsong ea ho etsa lehlaka la elektronike.
Ka Hlakubele 2021, mathata a tekheniki a kang ho putlama ha phofshoana (phofo e butsoang), ho se lekane ha li-interlayer bonding, volatilization eaaluminium, tlaase segokanyipalo, ho se leka-lekane transverse le longitudinal sebopeho thepa ea likarolo li ile tsa rarolloa ka tshebetso ya elektrone beam etsa TiAl motsoako.
Ntlafatso le ntlafatso ea liparamente tsa ts'ebetso bakeng sa ho lokisa likarolo tse rarahaneng tsa boholo bo boholo ka thekenoloji ea elektrone e qhibilihisang mochini oa khatiso oa 3d, taolo e lebisitsoeng ea ntlafatso ea microstructure ea thepa ka bophahamo bo fapaneng, le phetoho ea liparamente tsa ts'ebetso le maemo a khatiso, Ø110mm×66mm e teteaneng haholo ebile e se na pherekano ea Ti-48Alb-2Cr. Ho entsoe lintlafatso tse ncha likarolong tsa meralo e rarahaneng ea titanium le aluminium. Ka nako e ts'oanang, ka ho ntlafatsa tsela ea ho lekola le ho tsepamisa maikutlo, mokhoa oa ho theha likarolo tsa phetoho tse kobehileng o hlotsoe.

Ka ho ntlafatsa le ho ntlafatsa ts'ebetso ea preheating, molamu oa teko ea boholo bo phahameng o nang le ts'ebetso e ts'oanang libakeng tse fapaneng o hatisitsoe ka katleho.
