Iphrinta ye-Electron Beam encibilikisa i-3d

Insimbi ye-electron encibilika izingxenye zesakhiwo eziyinkimbinkimbi ze-titanium aluminium ephrinta ye-3D

I-alloy esekelwe ku-TiAl inezici zokuminyana okuphansi, amandla athile aphezulu, i-modulus ephezulu, ukumelana ne-oxidation lokushisa eliphezulu, njll., okungaba ngu-50% elula kune-nickel based superalloy.

Insimbi encibilikisa insimbi ye-electronUkuphrinta kwe-3Dubuchwepheshe bokulungiswa kwezinto ze-alloy ezisekelwe ku-TiAl njengendlela entsha futhi ethuthuke kakhulu yokwakha, kubhekwa njengendlela engcono kakhulu yokwenza izinto ze-alloy ezisekelwe ku-TiAl, kanye nokuncibilika kwayo okuyingqayizivele kwe-micro-zone, ukwelashwa kokushisa komjikelezo, ukuqiniswa okusheshayo nezinye izinzuzo zobuchwepheshe. Izinkinga zesakhiwo esimahhadlahhadla kanye nesakhiwo sokuqina esixegayo ekusakazeni, i-ingot metallurgy kanye ne-powder metallurgy ziyanqotshwa. Ngenxa yezici zayo, iletha izinselelo ezinkulu zobuchwepheshe enqubweni yokwenza ugongolo lwe-electron.

NgoMashi 2021, ubunzima bezobuchwepheshe obufana nokuwa kwempushana (impushana efuthayo), ukubophela kwe-interlayer okunganele, ukuvuvukai-aluminium, ukuminyana okuphansi, izakhiwo ezingalingani eziguquguqukayo kanye nezakhiwo ze-longitudinal zezingxenye zaxazululwa ngenqubo ye-electron beam eyenza i-TiAl alloy.

Ukuthuthukiswa nokuthuthukiswa kwamapharamitha wenqubo yokulungiselela izingxenye zesakhiwo ezinosayizi omkhulu ngosizo lwe-electron beam encibilikisa ubuchwepheshe bephrinta ye-3d, ukulawulwa okuhlosiwe kokuvela kwe-microstructure yezinto eziphakeme ezihlukene, nokuguqulwa kwamapharamitha wenqubo nezimo zokuphrinta, i-Ø110mm×66mm eminyene kakhulu futhi engaqhekeki i-Ti-48Alb-2Cr super-free. Ukuphumelela okusha kwenziwe ezingxenyeni zesakhiwo eziyinkimbinkimbi ze-titanium ne-aluminium. Ngesikhathi esifanayo, ngokuthuthukisa indlela yokuskena nokugxila kwendawo ye-beam, inqubo yokwenza izingxenye zokuguqula ezigobile ezinezindonga ezincane isinqotshiwe.

I-electron beam powder yaqhuma ngaso leso sikhathi

Ngokulungiselela nokuthuthukiswa kwenqubo yokushisisa kwangaphambili, induku yokuhlola usayizi ophezulu esebenza okufanayo ezindaweni eziphakeme ezihlukene iphrintwe ngempumelelo.

Ngemuva kokulawulwa kwezicubu eziphuzile, i-transverse kanye ne-longitudinal microstructure yesampula ye-Ti-48Al-2Cr-2Nb yayifana kakhulu, futhi ukuminyana kungafinyelela ngaphezu kwama-99.6%. Ithebula elilandelayo libonisa izakhiwo ezimaphakathi zebha yokuhlola evundlayo nelongitudinal.

Kubikwa ukuthi i-GE Aviation isimemezele ngokusemthethweni ukuthi injini ye-GE9XFAA isigunyazwe yi-Federal Aviation Administration (FAA), futhi injini inezingxenye zokukhiqiza ezingeziwe ezingaphezu kuka-300, lapho i-titanium aluminium low-pressure turbine blade eyakhiwe ubuchwepheshe be-electron beam selective melting ingenye yazo.
