The microscopy study showed the uniform distribution of reinforcements in the SiCp/Al–Mg–Mn–Cu composites. And a large number of fine CuMgAl2 phases were observed in the untreated sample but dissolved in the SS sample to some extent. It can be confirmed that the size and number of some new precipitates and CuMgAl2 phases were in the suitable state for the SA sample resulting from its excellent integrated mechanical properties. A good combination of strength and plasticity in SA sample was corresponding well with its much lower coefficient of friction (COF) and well abrasion resistance, with a COF of 0.25. The wear mechanisms of the untreated and SS samples have found to be the combination of abrasive and adhesive indicated by the presence of some wear debris and delaminated flakes, whereas the wear mechanism is changed to adhesive dominantly with slight delamination in case of SA sample.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141253998","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 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":null,"pages":null},"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":null,"pages":null},"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}

Tensile tests, hardness measurements, and SEM/EDS/EBSD analyses were conducted to reveal the characterization of dissimilar TWIP/304L steel joint. 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. This variation in the microstructure resulted in both ductile and brittle fractures.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141168351","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}

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. The increase in reinforcement weight percentage results in a decrease in the wear rate of reinforced composites, while wear rates for these composites exhibit a linear increase with a change in load from 10 to 20 N.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141148932","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}
