The effects of particle size, acid concentration, time, solid/liquid ratio, temperature, and mixing speed on the dissolution process of copper were investigated. According to the test results, optimum dissolution conditions are as follows: particle size was 74 µm; organic acid concentration was 0.2 mol/L; duration was 60 min; solid/liquid ratio was 1/10; the temperature was determined as 25 °C and the stirring speed was 300 rpm; and the copper extraction value was obtained as 73.18% under optimum experimental conditions. Kinetic models were applied to the dissolution efficiencies obtained to determine the dissolution kinetics of copper in the presence of organic acid, and it was found that the dissolution process was controlled by the film diffusion model. In light of the data obtained, it can be said that organic acid, which is an economical and environmentally friendly leaching reagent, can be used in the dissolution of copper from malachite ((text{Cu}(text{OH}{)}_{2}{text{CuCO}}_{3})), as well as in the leaching of other precious metals such as copper, zinc, and cobalt from oxide and carbonate ores.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"50 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141187864","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}

To increase the capability of the traditional neural networks in modeling and forecasting problems, the proposed deep ANN has two hidden layers that benefit from deep learning techniques to overcome well-known issues such as overfitting and gradient vanishing. The deep ANN predicted results were compared with the simulated and experimental hysteresis loops of the synthesized polyvinyl alcohol@CoFe2O4 nanocomposites obtained from the vibrating sample magnetometer and MC method. The interaction between polymer and nanoparticles, their structure, and morphology were analyzed employing Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy, and field emission scanning electron microscopy. Comparison between the hysteresis loops revealed that the deep ANN method that has been trained with the previous published data was successful in the prediction of the shape and coercive field of particles in a polymer matrix relative to the MC method, which considered only the uniaxial anisotropy and Zeeman energy of the nanoparticles. The coercivity and remanence magnetization measured with the accuracy of about 93.33% and 62.23% for deep ANN method and 80.76% and 66.66% for MC method, respectively.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"16 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141168170","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}

Oscillation of the laser beam resulted in layered marks in the fusion zone. These layered marks contain primary austenitic dendrites and inertinitic secondary austenite. Both steels exhibited narrow heat-affected zones. An interlayer of an unmixed zone was formed between the fusion zone and the heat-affected zone of 304L due to differences in their liquidus points. Some intergranular gaps were observed in the heat-affected zone of the TWIP steel. The maximum tensile strength, 561.3 MPa, was achieved at a laser power of 3600 W and a welding speed of 80 mm/s. All specimens failed from the fusion zone of the dissimilar joint due to high hardness difference and underfill induced notch effect. The hardness difference reached 51.4 Hv10 due to the heterogeneous composition of the fusion zone.

Micrographs revealed the uniform dispersion of TiC particles within the matrix, while Ni reacted with aluminum, forming the intermetallic compound Al3Ni, dispersed along the grain boundaries. The incorporation of TiC and Ni resulted in a considerable decrease in grain size from ~ 130 to ~ 49 µm. Notably, the incorporation of 3 wt% TiC and 6 wt% Ni (sample S(3,6)) exhibited a substantial increase in yield strength (YS), ultimate tensile strength (UTS), and hardness by 51.11%, 32.57%, and 46.96%, respectively, compared to the unreinforced sample S(0,0). The observed improvements in these properties can be ascribed to a mix of factors, including grain refinement, Al3Ni precipitate hardening, and dispersion hardening facilitated by the TiC particles.

In this study, tungsten inert gas (TIG) welding of 7075 Al alloy with newly developed 7075 Al alloy wire as filler is successfully carried out and the full-penetration and defect-free joint is formed. The fusion zone (FZ) is consisted of fine and equiaxed α-Al dendrites and a narrow transition zone (TZ) with columnar α-Al grains is formed between the heat-affected zone (HAZ) and FZ. The minimum hardness is obtained in FZ in 7075 Al alloy-welded joints and post-weld heat treatment (PWHT, solid solutioned at 480℃ for 1 h and then aging at 120℃ for 24 h) induces significant hardening in both FZ and HAZ due to the precipitation of GP zones and η' phase. The yield strength, ultimate tensile strength and ductility of as-welded joint are 223 MPa, 374 MPa and 4.6%, and they are improved to 435 MPa, 533 MPa and 7.8%, respectively, after PWHT.

The CCT curves collected from confocal laser scanning microscopy showed that the initial crystallization temperatures decreased with lower CaO/SiO2 mass ratios, and the primary crystal phases transformed from a merwinite phase (Ca3MgSi2O8) with a stronger crystallization ability to a melilite solid solution (Ca2Al2SiO7–Ca2MgSi2O7) with a comparatively weaker crystallization ability, which correlates well with the variation of Mg/Al mole ratios in melilite and verifies the formation of Ca2MgSi2O7 as one of the main reasons for the poor fluidity of the slag. Furthermore, a higher viscosity was observed for modified slags with CaO/SiO2 mass ratios from 1.34 to 1.05, accompanied by the activation energy increased from 173.0 to 182.7 kJ/mol, which is consistent with the decreased NBO/Si value and the increased Q3/Q2 ratio detected by Raman spectra. The crystal phase with melting point higher than the discharged temperature and the enhanced degree of polymerization of the slag structure will lead to the poor fluidity of the slag, which should be emphasized in the actual modification of the blast furnace slag.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"193 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140934788","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}
