Electron beam melting 3D luam ntawv titanium aluminium complex structural qhov chaw
Tial raws li alloy muaj cov yam ntxwv ntawm qhov ceev, muaj lub zog muaj zog, thiab lwm yam, uas yog kwv yees li ntawm Nickel raws Superalloy.
Electron beam melting hlau3D luam ntawv thev naus laus zis rau kev npaj ntawm TiAl raws li cov ntaub ntawv alloy raws li cov txheej txheem tshiab thiab qib siab tshaj plaws, suav tias yog qhov kev xaiv zoo tshaj plaws rau kev tsim TiAl raws li cov ntaub ntawv alloy, thiab nws qhov tshwj xeeb micro-zone melting, cycle tshav kub kho, ceev solidification thiab lwm yam zoo technologies. . Cov teeb meem ntawm cov qauv ntxhib thiab xoob solidification qauv hauv casting, ingot metallurgy thiab hmoov metallurgy tau kov yeej. Vim nws tus yam ntxwv, nws coj cov kev sib tw loj heev rau cov txheej txheem tsim hluav taws xob.
Nyob rau lub Peb Hlis 2021, cov teeb meem kev nyuaj xws li hmoov av tawg (muab hmoov), tsis txaus interlayer bonding, volatilization ntawmaluminium, low density, uneven transverse and longitudinal structure properties of parts were solved in the process of electron beam forming TiAl alloy.
Kev ua kom zoo thiab txhim kho cov txheej txheem tsis zoo rau kev npaj cov txheej txheem loj loj los ntawm electron beam melting 3d tshuab luam ntawv thev naus laus zis, tsom kev tswj hwm ntawm microstructure evolution ntawm cov khoom ntawm qhov siab sib txawv, thiab kev hloov kho ntawm cov txheej txheem tsis thiab luam ntawv, Ø110mm × 66mm tuab heev thiab tawg-dawb Ti-48Al-2Cr-2Nb supercharger turbine tau ua tiav. Kev tawg tshiab tau ua nyob rau hauv titanium thiab aluminium complex structural qhov chaw. Nyob rau tib lub sij hawm, los ntawm optimizing txoj kev scanning thiab beam chaw tsom, cov txheej txheem ntawm nyias-walled nkhaus hloov qhov chaw tau kov yeej.
Electron beam hmoov tawg instantaneously
Los ntawm kev ua kom zoo dua qub thiab txhim kho cov txheej txheem preheating, qhov ntsuas qhov siab loj nrog tib qhov kev ua tau zoo ntawm qhov siab sib txawv tau ua tiav tiav.

Tom qab qhov kev cai ntawm cov ntaub so ntswg lig, qhov transverse thiab longitudinal microstructure ntawm Ti-48Al-2Cr-2Nb cov qauv yog ntau yam sib xws, thiab qhov ceev tuaj yeem ncav cuag ntau dua 99.6%. Cov lus hauv qab no qhia qhov nruab nrab txhua yam khoom ntawm lub transverse thiab longitudinal test bar.
| Kub | Yield zog | Tensile zog | Tus nqi ntawm elongation |
| 650 ° C | ≥410 | ≥500 | ≥1.2 |
| Chav kub | ≥430 | ≥510 | ≥1.8 |

Nws tau tshaj tawm tias GE Aviation tau tshaj tawm tias lub cav GE9XFAA tau lees paub los ntawm Tsoom Fwv Tebchaws Aviation Administration (FAA), thiab lub cav muaj ntau tshaj 300 qhov chaw tsim khoom ntxiv, ntawm cov titanium aluminium low-pressure turbine hniav tsim los ntawm electron beam. selective melting technology yog ib tug ntawm lawv.
