The K2TiF6 flux content in the composites varied between 40 and 100% of a constant B4C content (6 wt.%). The heat treatment consisted of solutionizing at 540 °C for 8 h, followed by water quenching and then artificially aging at 180 °C for 4 h. While at any applied load, the wear rate decreased with increasing ex situ B4C particle retention, at applied loads more than 20 N, the wear performance deteriorated due to increased fracture and dislodgement of B4C particles. In situ Al-Ti intermetallics were more effective in lowering the wear rate at high applied loads. A mechanically mixed layer (MML) consisting of self-lubricating boron oxide and boric acid was formed in composites with high B4C particle retention, lowering the friction coefficient up to 20 N applied load. However, the friction coefficient increased at a higher applied load of 30 N due to increased peeling off the MML and three-body wear.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"187 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253633","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}

This study systematically evaluated the impact of varying Ga concentrations on the microstructural evolution and mechanical response of dual-phase heterostructured Ag-49 wt.%Cu-xGa (x = 0, 5, 7, and 10 wt.%) alloys. The study utilized scanning electron microscopy (SEM) and nanoindentation experiments to analyze the structure evolution and hardness changes in Ag-Cu-Ga alloys. The results revealed that the volume fraction of the hard domains (Cu-rich phases) and the hardness increased as the Ga content increased. This increase in Ga content led to a greater degree of mechanical incompatibility between the soft and hard domains, ultimately enhancing the mechanical properties of Ag-Cu-Ga alloys. Through the implementation of a loading–unloading–reloading (LUR) test, it was shown that the Ag-49Cu-7Ga specimens exhibited higher levels of hetero-deformation-induced (HDI) stresses compared to the Ag-49Cu specimens that did not contain Ga elements. This difference can be attributed to the solid solution strengthening effect of Ga. Through the use of digital imaging technique (DIC), it has been discovered that the introduction of Ga element into the Ag-Cu-Ga specimen results in the formation of dispersed strain bands on the surface. These strain bands effectively absorb and distribute the applied strains, resulting in the Ag-49Cu-7Ga specimen exhibiting both high strength and good plasticity.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"9 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253634","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}

Researchers are exploring advanced manufacturing processes that can further enhance the performance of this material. Therefore, the cryogenic treatment of ISO coded K06 WC–Co cemented carbide was studied by uniform design experiment. The equation of the effect of cryogenic treatment on the properties of cemented carbide was fitted by multivariate quadratic nonlinear regression. The phase composition, grain size, and residual stress of the material were analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results indicate that cryogenic treatment significantly changes the residual stress of WC grains, accompanied by a phase transition of the bonding phase (Co phase). However, cryogenic treatment has no significant effect on the grain size of the material. The wear resistance and impact toughness of cemented carbide have been significantly improved. At the same time, the wear scar and impact fracture of the material were observed, and the mechanism of impact fracture was analyzed. The residual compressive stress of the WC phase increased by about 120% and the rockwell hardness of the material increased by about 2.61% after cryogenic treatment, but the increase was insignificant. However, the wear resistance increased by about 88.89% and the impact toughness increased by about 19.30%.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"2 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253637","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}

Microstructural analysis revealed that DCT reduced the sample porosity from 1.05 to 0.36%. In terms of mechanical properties, the DCT samples exhibited tensile and yield strengths of 736 MPa and 541 MPa, respectively, which are significantly higher than those of conventionally cast parts. The elongation reached 59%, a crucial factor for applications requiring material flexibility. However, fatigue test results showed a reduction in the fatigue performance of DCT samples. The fatigue limit was predicted using extreme value statistical analysis and sample sectioning methods, with the prediction error within 10%. The Kitagawa–Takahashi diagram and EI-Haddad model were used to evaluate the safety performance of the material, and the critical defect sizes of the samples were determined.

These two bands appeared as γ/α2 lamellar with random lath orientation under high magnification, with different lamellar spacing of 210 and 380 μm, respectively. Unmelted Ti2AlNb particles could be found in the lamellar colony band, which could decrease the dislocation density further to increase the strength. The tensile strength at room temperature reaches 541-543 MPa, with a corresponding elongation of 0.6-0.8%, while the fracture occurs mainly in the equiaxed grain bands with a translocation fracture mechanism. Hardness tests also showed higher hardness values in the lamellar colony bands than in the equiaxial grain bands. CT characterization tests did not reveal that fracture cracks started or passed through the Ti2AlNb grains.
