I Iulai 13, 2023, Polofesa Gang Wang 'au i le Inisetiute o Materials Suesuega o le Iunivesite o Shanghai lomia latou suesuega aupito lata mai taunuuga "Microstructural evolution ma meatotino masini o (FeCoNi) 85.84Al7.07Ti7.09 maualuga-entropy uʻamea e filifili leisa liusuavai ma togafitiga matua", lea e faʻaaogaina ai le faʻaogaina o le gaosiga faʻapipiʻi sili ona lelei ma le faʻagasologa o le soifua matua mo taimi pupuu e gaosia ai ((FeCoNi) 85.84Al7.07Ti7.09) faʻapipiʻi maualuga-entropy.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 malologa o le 11.6%.O Polofesa Jia Yandong ma Dr. Mu Yongkun o tusitala 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 auala faʻamalosia, faʻamalosia faʻamalosi ma le faʻamalosia o timuga, na faʻalauiloaina i le FCNAT HEA faʻaaogainaSLMmetotia ma togafitiga tuai mo taimi pupuu ile 780°C.O le iʻuga, o le tuʻufaʻatasia o faʻalavelave maualuga ma faʻalavelave faʻalavelave e mafai ona ausia i le FCNAT 780, e maua ai mea faʻainisinia sili ona lelei (malosi malosi σ0.2, malosi malosi σUTS, ma le faʻalauteleina i le gau εf tau o le 1214 MPa, 1625 MPa , ma le 11.6%, i le faasologa).
(2) O vaega o fatuga o leSLMfa'ata'ita'iga ma fa'ata'ita'iga tuai e tele lava ina fa'avaeina 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.
