Electron danda kunyunguduka 3D kudhinda titanium aluminium yakaoma zvimiro zvikamu
TiAl based alloy ine hunhu hwehushoma density, yakakwirira chaiyo simba, yakakwira modulus, yakakwira tembiricha oxidation kuramba, nezvimwewo, iyo inenge 50% yakareruka pane nickel based superalloy.
Erekitironi danda rinonyunguduka simbi3D kudhindatekinoroji yekugadzirira TiAl based alloy materials senzira itsva uye yakanyanyisa kuumba nzira, inoonekwa seyakanakisa sarudzo yekugadzira TiAl based alloy materials, uye yakasarudzika micro-zone kunyunguduka, kutenderera kupisa kurapwa, kukurumidza kusimba uye zvimwe zvakanakira tekinoroji. Matambudziko eyakaomarara chimiro uye yakasununguka kusimba chimiro mukukanda, ingot simbi uye poda simbi inokundwa. Nekuda kwehunhu hwayo, inounza matambudziko makuru ehunyanzvi kune erekitironi danda rekugadzira maitiro.
Muna Kurume 2021, matambudziko ehunyanzvi akadai sekudonha kwehupfu (kuvhuvhuta hupfu), kusakwana interlayer bonding, volatilization yealuminium, yakaderera density, kusaenzana transverse uye longitudinal chimiro zvimiro zvezvikamu zvakagadziriswa mukuita kwe electron danda kuumba TiAl alloy.
Kugonesa uye kukwidziridzwa kwemaitiro maparamendi ekugadzirira yakakura-saizi yakaoma zvimiro zvikamu neelectron beam kunyunguduka 3d printer tekinoroji, yakanangwa mutemo weiyo microstructure shanduko yezvinhu pahurefu hwakasiyana, uye kugadziridzwa kwemaitiro maparamendi uye mamiriro ekudhinda, iyo Ø110mm×66mm yakanyanya dense uye isina crack-isina Ti-48Alb-2Cr yakabudirira. Kubudirira kutsva kwakaitwa mutitanium uye aluminium yakaoma zvimiro zvikamu. Panguva imwecheteyo, nekugadzirisa nzira yekuongorora uye danda rekutarisa, nzira yekugadzira yeatete-madziro akakomberedzwa ekuchinja zvikamu akakundwa.
Electron beam poda yakaputika pakarepo
Kuburikidza nekugadzirisa uye kukwidziridzwa kwe preheating process, iyo yakakwira saizi yekuyedza tsvimbo ine kuita kwakafanana pakureba kwakasiyana kwakadhindwa zvakabudirira.

Mushure mekupedzisira kwetishu regulation, iyo transverse uye longitudinal microstructure yeTi-48Al-2Cr-2Nb specimen yakanga yakawanda yunifomu, uye density inogona kusvika kupfuura 99.6%. Iyi tafura inotevera inoratidza avhareji yemakanika zvivakwa zveiyo transverse uye longitudinal test bar.
| Tembiricha | Goho simba | Kusimba simba | Rate of elongation |
| 650°C | ≥410 | ≥500 | ≥1.2 |
| Tembiricha yekamuri | ≥430 | ≥510 | ≥1.8 |
Mechanical zvimiro zveTi-48Al-2Cr-2Nb poda yakadhindwa neelectron beam tekinoroji.

Zvinonzi GE Aviation yakazivisa zviri pamutemo kuti injini yeGE9XFAA yakasimbiswa neFederal Aviation Administration (FAA), uye injini ine zvinopfuura mazana matatu ekuwedzera ekugadzira zvikamu, izvo titanium aluminium low-pressure turbine blade inogadzirwa neelectron beam selective melting tekinoroji ndeimwe yacho.
