Ku ya 13 Nyakanga 2023, itsinda rya Prof. Gang Wang mu kigo cy’ubushakashatsi bw’ibikoresho bya kaminuza ya Shanghai ryashyize ahagaragara ibyavuye mu bushakashatsi bwabo "Ubwihindurize bwa Microstructural hamwe n’imiterere ya (FeCoNi) 85.84Al7.07Ti7.09 ivanze na entropiya yo mu bwoko bwa lazeri yatoranijwe gushonga hamwe kuvura gusaza ", ikoresha uburyo bunoze bwo kongera inyongeramusaruro nuburyo bwo gusaza mugihe gito kugirango bitange umusaruro ((FeCoNi) 85.84Al7.07Ti7.09) all-entropy alloy.FeCoNi) 85.84Al7.07Ti7.09 all-entropy alloy, yerekana imiterere yubukanishi buhebuje, ifite imbaraga zidasanzwe zingana na 1625 MPa, umusaruro utanga MPa 1214, hamwe no kurambura kumena 11,6%.Porofeseri Jia Yandong na Dr. Mu Yongkun ni abanditsi bahuje.
Ibisubizo by'ingenzi
Uyu murimo wakoze ubushakashatsi ku ngaruka zo kuvura gusaza ku ihindagurika rya microstructural n'imiterere ya (FeCoNi) 85.84Al7.07Ti7.09HEA yakozwe naSLM.Hafashwe imyanzuro ikurikira.
(1) Uburyo bubiri bwo gushimangira, gushimangira dislocation no gushimangira imvura, byatangijwe muri FCNAT HEA hakoreshejweSLMtekinike no kuvura gusaza igihe gito kuri 780 ° C.Nkigisubizo, guhuza dislokisiyo nyinshi hamwe nicyiciro cyimvura birashobora kugerwaho muri FCNAT 780, bikavamo uburyo bwiza bwubukanishi (gutanga imbaraga σ0.2, imbaraga zidasanzwe za σUTS, no kurambura kumena εf agaciro ka 1214 MPa, 1625 MPa , na 11,6%, uko bikurikirana).
(2) Icyiciro kigizwe naSLMibyitegererezo hamwe nabasaza byintangarugero byari bigizwe ahanini nicyiciro cya FCC, L12 na L21.Nyuma yo kuvura gusaza, ibyiciro bya L12 na L21 byaguye kandi ibikubiye mu byiciro bya L12 na L21 byagabanutse buhoro buhoro hamwe no kwiyongera kwubushyuhe bwo kuvura.
Niba ushaka kumenya amakuru menshi kandi ukeneye gukora moderi yo gucapa 3d, nyamuneka hamagaraJSADD Uruganda rwa 3Digihe cyose.
