I le aso 13 o Iulai, 2023, o le vaega a Prof. Gang Wang i le Inisetiute o Mea Suesuega a le Iunivesite o Shanghai na lomia a latou suʻesuʻega aupito lata mai "Microstructural evolution ma mea faʻainisinia o (FeCoNi) 85.84Al7.07Ti7.09 maualuga-entropy alloy e ala i le faʻafefeteina leisa filifilia ma togafitiga tuai", lea e faʻaaogaina ai le faʻagasologa o le gaosiga o le faʻaopoopoga puupuu ma le faʻaogaina ((FeCoNi)85.84Al7.07Ti7.09) maualuga-entropy alloy. FeCoNi) 85.84Al7.07Ti7.09 uʻamea maualuga-entropy, o loʻo faʻaalia ai mea faʻainisinia sili ona lelei, faʻatasi ai ma le malosi sili o le tensile o le 1625 MPa, o le malosi o le 1214 MPa, ma le faʻalauteleina i le malepelepe o le 11.6%. Polofesa Jia Yandong ma Dr. Mu Yongkun o tusitala tutusa tutusa.
Sailiga autu
O lenei galuega na suʻesuʻeina le aʻafiaga o togafitiga tuai i luga o le microstructural evolution ma mea faʻainisinia o (FeCoNi) 85.84Al7.07Ti7.09HEA na gaosia eSLM. O fa'ai'uga nei na faia.
(1) E lua faiga faʻamalosia, faʻamalosi faʻamalosi ma le faʻamalosia o timuga, na faʻalauiloaina i le FCNAT HEA faʻaaogainaSLMmetotia ma togafitiga tuai mo taimi pupuu ile 780°C. O se taunuuga, o se tuufaatasiga o le maualuga-density dislocations ma precipitated vaega e mafai ona ausia i le FCNAT 780, e maua ai i meatotino sili ona lelei (o le malosi σ0.2, malosi tensile mulimuli σUTS, ma elongation i gau εf tau o le 1214 MPa, 1625 MPa, ma le 11).
(2) O vaega o fatuga o leSLMfa'ata'ita'iga ma fa'ata'ita'iga tuai sa tele lava ina fa'avae mai vaega FCC, L12 ma L21 vaega. Ina ua maeʻa togafitiga tuai, L12 ma L21 vaega na faʻafefe ma faʻaitiitia le anotusi o vaega L12 ma L21 faʻatasi ma le faʻatupulaia o le vevela o togafitiga tuai.
Afai e te fia iloa nisi faʻamatalaga ma manaʻomia le faia o le faʻataʻitaʻiga lolomi 3d, faʻamolemole faʻafesoʻotaʻiJSADD 3D Manufacturertaimi uma.
