Electron umqadi ukunyibilika 3D yoshicilelo titanium aluminiyam entsonkothileyo izahlulo zesakhiwo
I-alloy esekelwe kwi-TiAl ineempawu zoxinaniso oluphantsi, amandla athile aphezulu, imodyuli ephezulu, ukumelana nobushushu obuphezulu be-oxidation, njl., Emalunga ne-50% elula kune-nickel based superalloy.
Intsimbi ye-electron enyibilikayoUshicilelo lwe-3Ditekhnoloji yokulungiswa kwezixhobo ze-alloy ezisekelwe kwi-TiAl njengendlela entsha kunye neyona ndlela iphambili yokwenza, ithathwa njengeyona nto ingcono kakhulu yokwenza izinto ze-alloy ezisekelwe kwi-TiAl, kunye ne-micro-zone yayo ekhethekileyo yokunyibilika, ukunyangwa kobushushu bomjikelezo, ukuqina ngokukhawuleza kunye nezinye iingenelo zobuchwepheshe. Iingxaki zolwakhiwo olurhabaxa kunye nolwakhiwo oluxengaxengayo lokuqina ekujuleni, i-ingot metallurgy kunye ne-powder metallurgy zoyiswa. Ngenxa yeempawu zayo, izisa imingeni enkulu yobugcisa kwinkqubo yokwenza umqadi we-electron.
NgoMatshi ka-2021, ubunzima bobugcisa obufana nokuwa komgubo (umgubo ovuthuzayo), ukungonelanga kwe-interlayer bonding, ukuguquguqukaaluminiyam, Uxinaniso oluphantsi, ukungalingani okunqamlezileyo kunye neepropati zesakhiwo se-longitudinal zamalungu zasonjululwa kwinkqubo ye-electron beam eyenza i-alloy ye-TiAl.
Ukuphucula kunye nokuphuculwa kweeparameters zenkqubo yokulungiselela iindawo ezinkulu zesakhiwo esiyinkimbinkimbi nge-electron beam yokunyibilika iteknoloji ye-3d yomshicileli, ukulawulwa okujoliswe kuyo kwe-microstructure evolution yezinto eziphakamileyo ezahlukeneyo, kunye nokuguqulwa kweeparameters zenkqubo kunye neemeko zokushicilela, i-Ø110mm×66mm exinene kakhulu kunye ne-crack-free Ti-48Alb-2Cr . Ukuphumelela okutsha kwenziwe kwi-titanium kunye ne-aluminiyam eyinkimbinkimbi yezakhiwo. Kwangaxeshanye, ngokulungiselela indlela yokuskena kunye nokugqalwa kwebala le-beam, inkqubo yokuyila yamacandelo amancinci anodonga olugobileyo yoyiswe.
I-electron beam powder yagqabhuka ngoko nangoko
Ngokuphucula kunye nokuphuculwa kwenkqubo yokufudumeza, intonga yovavanyo oluphezulu kunye nokusebenza okufanayo kwiindawo eziphakamileyo ezahlukeneyo ishicilelwe ngempumelelo.

Emva kokulawulwa kwezicubu ezisemva kwexesha, i-microstructure ye-transverse kunye ne-longitudinal ye-specimen ye-Ti-48Al-2Cr-2Nb yayifana kakhulu, kwaye ubuninzi bungafikelela ngaphezu kwe-99.6%. Le theyibhile ilandelayo ibonisa iipropathi ze-avareji zomatshini webha yovavanyo olunqamlezayo kunye nobude.
| Ubushushu | Unikeze Amandla | Tensile strength | Umlinganiselo wobude |
| 650°C | ≥410 | ≥500 | ≥1.2 |
| Ubushushu begumbi | ≥430 | ≥510 | ≥1.8 |
