Musi waChikunguru 13, 2023, timu yaProfessor Gang Wang kuInstitute of Materials Research yeShanghai University yakaburitsa tsvakiridzo yavo yazvino "Microstructural evolution and mechanical properties of (FeCoNi)85.84Al7.07Ti7.09 high-entropy alloy by selective laser melting with. kuchembera kurapwa", iyo inoshandisa yakanyatsoshanda yekuwedzera yekugadzira maitiro uye yenguva pfupi yekuchembera kugadzira ((FeCoNi)85.84Al7.07Ti7.09) yakakwirira-entropy alloy.FeCoNi)85.84Al7.07Ti7.09 high-entropy alloy, iyo inoratidza yakanakisa mechanical zvivakwa, ine yekupedzisira tensile simba re1625 MPa, simba regoho re1214 MPa, uye elongation pakutyora kwe11.6%.Purofesa Jia Yandong naDr. Mu Yongkun ndivo vanyori vanowirirana.
Zvakawanikwa zvakakosha
Iri basa rakaongorora mhedzisiro yekurapa kuchembera pane microstructural evolution uye mechanical properties ye (FeCoNi)85.84Al7.07Ti7.09HEA inogadzirwa neSLM.Mhedziso dzinotevera dzakaitwa.
(1) Nzira mbiri dzekusimbisa, kusimuka kusimbisa uye kusimba kwemvura, dzakaunzwa muFCNAT HEA uchishandisa.SLMnzira uye kurapwa kwenguva pfupi kuchembera pa780 ° C.Nekuda kweizvozvo, musanganiswa we-high-density dislocations uye nhanho dzemvura inogona kuwanikwa muFCNAT 780, zvichikonzera optimal mechanic properties (goho simba σ0.2, yekupedzisira tensile simba σUTS, uye elongation pakutyora εf kukosha kwe1214 MPa, 1625 MPa , uye 11.6%, zvichiteerana).
(2) Chikamu chekuumbwa kweSLMmasampuli uye masampuli ekare ainyanya kuumbwa neFCC chikamu, L12 uye L21 zvikamu.Mushure mekurapa kwekuchembera, L12 uye L21 zvikamu zvakaderedzwa uye zvirimo zveL12 uye L21 zvikamu zvishoma nezvishoma zvakadzikira nekuwedzera kwekuchembera kwekushisa kwekurapa.
Kana iwe uchida kuziva rumwe ruzivo uye uchida kugadzira 3d printing modhi, ndapota tauraJSADD 3D Mugadziringuva dzese.
