The macroscopic analyses were done for isotopic material with a non-linear hardening using the UMAT user material procedure. The pure Lagrangian approach was applied here. The stress, strains and their increments, as well as, the deformation gradient tensor were recorded for selected finite elements in each calculation step. The displacements obtained in the macroscopic FEM analysis are then used as the kinematic input for the polycrystalline structure. The dislocation slip was included as the source of the plastic deformation here for the face-centered cubic structure. The results obtained with the use of the crystal plasticity show the heterogeneous distribution of stress and strain within the material associated with the grains anisotropy. The results in both micro-and macro-scales are coincident. The FEM analyses show the potential of the application of the crystal plasticity approach for solving elastic-plastic problems including the material forming processes.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"119 43","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study takes advantage of good wettability of ag-Cu-Pd brazing alloy to suppress brittle Fe-nb intermetallic formation, hence improve the joints’ mechanical performance. The wettability of ag-Cu-Pd filler metal on niobium, the interface microstructure and mechanical properties of the transition joints were investigated. Two kinds of ag-Cu-Pd filler metals had been studied and wet well on the niobium, and the wettability of ag-31.5Cu-10Pd filler metal on niobium was better than ag-28Cu-20Pd filler metal. Microstructure characterization demonstrated the absence of brittle intermetallic layers in all of the joint interfaces. Mechanical properties of samples prepared with ag-31.5Cu-10Pd filler metal were also better than their peers made with ag-28Cu-20Pd filler metal both room temperature (300 K) and liquid nitrogen temperature (77 K). The transition joints displayed shear strengths of 356-375 MPa at 300 K and 440-457 MPa at 77 K, respectively. after undergoing ten thermal cycles between the room temperature and the liquid nitrogen temperature, the transition joints’ leak rates were all lower than 1.1×10 –11 mbar·L/s. Therefore, ag-Cu-Pd filler metal is applicable to high vacuum vessels used at cryogenic temperatures.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":" 12","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138961520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three microtextured grooves with a spacing of 500, 750, and 1000 μm were prepared on the surface of WC-8Co cemented carbide. TiAlCrSiN multi-element hard coating was deposited on the WC-8Co cemented carbide microtextured surface with multi-arc ion plating technology. The Vickers hardness and fracture toughness of coated and uncoated WC-8Co cemented carbide with or without a microtextured surface were investigated. The effect of different microtextured spacing on the interface bonding strength of the TialCrSin coating was analyzed. The results show that with the reduction of the microtextured spacing, the Vickers hardness of the cemented carbide slightly decreases, and the fracture toughness slightly increases. The microtextured surface can improve the interface bonding strength between the coating and the substrate. The smaller the microtextured spacing, the larger the specific surface area and the higher the surface energy, so the interface bonding strength between the coating and the substrate increases.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"115 19","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
