Electron mtengo wosungunula 3D kusindikiza titaniyamu zotayidwa zovuta structural zigawo
TiAl based alloy ili ndi mawonekedwe otsika kachulukidwe, mphamvu zenizeni zenizeni, modulus yayikulu, kukana kwa okosijeni kutentha kwambiri, ndi zina zambiri, zomwe zimakhala zopepuka 50% kuposa superalloy ya faifi tambala.
Elektroni mtengo wosungunula chitsulo3D kusindikizaluso pokonzekera TiAl zochokera aloyi zipangizo monga njira yatsopano ndi zapamwamba kwambiri kupanga, amaona kuti kusankha bwino kupanga TiAl zochokera aloyi zipangizo, ndi wapadera yaying'ono zone kusungunuka, mkombero kutentha mankhwala, kulimba mofulumira ndi ubwino zina zamakono. Zovuta zamapangidwe owoneka bwino komanso mawonekedwe okhazikika olimba pakuponya, zitsulo za ingot ndi zitsulo za ufa zimathetsedwa. Chifukwa cha mawonekedwe ake, zimabweretsa zovuta zaukadaulo pakupanga ma elekitironi.
Mu Marichi 2021, zovuta zaukadaulo monga kugwa kwa ufa (ufa wowomba), kulumikizana kosakwanira kwa interlayer, kuphulika kwaaluminiyamu, otsika kachulukidwe, m'njira yopingasa ndi longitudinal kapangidwe katundu wa mbali zinathetsedwa mu ndondomeko elekitironi mtengo kupanga TiAl aloyi.
Kukhathamiritsa ndi kukweza ndondomeko magawo pokonzekera zikuluzikulu kukula zovuta structural mbali ndi elekitironi mtengo kusungunuka 3d chosindikizira luso, akulimbana malamulo a microstructure kusinthika kwa zipangizo pa mtunda wosiyana, ndi kusinthidwa kwa magawo ndondomeko ndi zinthu kusindikiza, ndi Ø110mm × 66mm wandiweyani kwambiri ndi wopanda mng'alu-free Ti-48Alb-2Cr Kupambana kwatsopano kwapangidwa mu titaniyamu ndi zigawo za aluminiyamu zovuta. Pa nthawi yomweyo, ndi optimizing njira sikani ndi mtengo malo kuyang'ana, kupanga njira woonda-mipanda yokhotakhota kusintha wagonjetsedwa.
Elektroni mtengo ufa unaphulika nthawi yomweyo
Kupyolera mu kukhathamiritsa ndi kukweza kwa preheating ndondomeko, mkulu mlingo woyesera ndodo ndi ntchito yomweyo pa mtunda osiyana yasindikizidwa bwino.
Electron mtengo wosindikiza wa 3D kutalika 90mm Ti-48Al-2Cr-2Nb ndodo yoyeserera
Pambuyo pa kayendetsedwe ka minofu mochedwa, mawonekedwe ozungulira ndi aatali a Ti-48Al-2Cr-2Nb anali ofanana kwambiri, ndipo kachulukidwe kake kakhoza kufika kuposa 99.6%. Gome lotsatirali likuwonetsa kuchuluka kwamakina amtundu woyeserera wodutsa ndi wautali.
| Kutentha | Zokolola mphamvu | Kulimba kwamakokedwe | Mlingo wa elongation |
| 650 ° C | ≥410 | ≥500 | ≥1.2 |
| Kutentha kwachipinda | ≥430 | ≥510 | ≥1.8 |
Makina amtundu wa Ti-48Al-2Cr-2Nb ufa wosindikizidwa ndi ukadaulo wa electron mtengo
Electron mtengo kupanga Ø110mm×66mm Ti-48Al-2Cr-2Nb aloyi turbocharger
Electron mtengo wosindikiza wa 3D kutalika 90mm Ti-48Al-2Cr-2Nb ndodo yoyeserera
Akuti GE Aviation yalengeza movomerezeka kuti injini ya GE9XFAA yatsimikiziridwa ndi Federal Aviation Administration (FAA), ndipo injiniyo ili ndi zowonjezera zowonjezera 300, zomwe tsamba la titaniyamu yotsika mphamvu ya turbine yopangidwa ndi teknoloji yosungunuka ya electron ndi imodzi mwa izo.
