The process begins with the extraction of elements from aluminium black dross, controlled heating at 680 °C leverages residue heat resources, essential in optimizing resource utilization. Further alkali metal halides addition is done to significantly enhance efficiency in melting aluminium–low magnesium (≤ 1%) scraps. Optimization in filtration was conducted at 900 RPM and temperatures near 50 °C to refine the purification process and eliminate impurities. Slow calcination was done at 100 °C for over 40 min, the salt cake allowing dissolution in a 3 M NaOH solution to achieve a critical pH value of 11.72. The precise pH neutralization was done by using a 3:1 H2SO4 solution to form aluminium hydroxide through the precipitation method at a pH level of 7, a pivotal precursor in alumina extraction. A detailed analysis of post-low-temperature calcination, ranging from room temperature to 800 °C for 10 min, was done. Furthermore, a thorough examination of residues and extracted γ- and θ-alumina was done using XRD, SEM–EDS, and ICP-OES techniques. About 79% of alumina was recovered from black aluminium dross. The proposed technique extracted alumina with a purity of 94.9% with a particle size of 318 nm.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"41 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609062","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}

At ~ 600 ppm inhibitor concentration, corrosion rate and inhibition efficiency are found to be ~ 0.18 ± 0.1 mpy and ~ 94%, respectively. The superior corrosion inhibition is due to the adsorption of the phytochemicals onto the metallic surface, as confirmed from spectroscopic analysis. Findings show the suitability of the black seed extract for practical applications at neutral pH and room temperature. AFM and magnetic force microscopy indicate lower surface roughness and nearly pristine topography for the inhibitor-protected specimens. In situ AFM analyses indicate delayed formation of surface irregularities for the inhibitor-protected specimens.

The effect of different cooling media such as water, air and furnace on the microstructure evolution and mechanical characteristics of the HSLA steel was evaluated. The hierarchical microstructures of HSLA steel were investigated by different microstructural characteristic techniques to draw a correlation between microstructure and mechanical properties. The HSLA steel exhibits predominantly martensitic microstructure with or without bainite irrespective of the cooling media. However, the morphology of the martensite was found to be dependent on the cooling rate. The effect of cooling medium on grain size was systematically shown by reconstruction of prior austenite grain boundaries from electron back-scattered diffraction investigation. Faster cooling results in higher yield and tensile strength due to predominant martensitic structure while relatively slower cooling rates result in comparatively lower strength values with a corresponding increase in ductility. This is attributed to the presence of retained austenite in the HSLA steel with decreasing cooling rate. An impact toughness of ≥ 50 J was obtained at subambient temperature of − 40 °C irrespective of the cooling rate.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"25 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568331","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}

Many driveshaft manufacturers prefer friction welding due to its relatively cheaper cost and ease of the process. However, they should meet some property-related criteria to achieve the expected lifetime. The forging technique becomes essential to succeed in these mechanical requirements. A comparative study evaluates the performance of constant velocity joints (CVJs) produced by multi-step warm–cold forging and friction welding processes. Medium carbon steels were used in both of the techniques. The microstructures, mechanical properties (i.e. hardness, strength, impact energy and shear strength), low-cycle fatigue (LCF) properties, wear resistance and cost-efficiency (number of operations, material saving, number of produced components and cost) are compared in detail for an industrial production point of view. The experimental results reveal that warm–cold forged specimens exhibit superior mechanical properties such as increased strength, hardness, relatively higher impact energy, improved shear strength, relatively longer LCF life and enhanced wear resistance (lower wear volume loss). In addition, it is also assessed that warm–cold forging is a more cost-effective manufacturing process (reduced weight, decreased number of operations and increased yield) in the production of CVJs compared to the friction welding process.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"22 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568333","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 dissolution kinetics of copper from low-grade goldfieldite ore was examined in ammonia–ammonium sulfate media. In this study, the influences of leachant concentration, reaction temperature, and particle size on goldfieldite ore dissolution were considered. Thus, the experimental results affirmed that the dissolution rate increases steadily with increase in leachant concentration, reaction temperature, and decreasing particle sizes. At established conditions (0.5 mol/L NH3–(NH4)2SO4; 75 °C; and 45 µm), 89.9% dissolution efficiency was achieved within 120 min. The activation energy (Ea) and reaction order calculated to be 34.8 kJ/mol and 1.045 supported the diffusion control mechanism with a first-order relation. Hence, the pregnant leach solution obtained at the optimal leaching conditions was accordingly treated and beneficiated to produce a high-grade copper chloride (CuCl2: 00-348-1947), recommended for various industrial utilities.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"40 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568332","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 current study presents a modified version of a unique experimental set-up for a perforated substrate sheet with ball-milled, nano-scale clad powder reinforcement. To create the clad material, Al2O3, SiC nano-sized grain powders and Mg coarse grain powder were combined with fine Al powder particles using a ball milling technique. In parallel, SS316L substrate sheets were utilised to fabricate bimetallic composite sheets and were perforated at regular intervals for a specific area. In an inert gas environment, a conventional heating process with mild initial compaction was offered for the sintering process to progress upon. The influence of the processing on the interfaces is suggested by the microstructure, energy-dispersive X-ray (EDX) and micro-hardness results from different sites in the synthesised bimetallic composite sheet. The processing methods and how they affect the diffusion behaviour of the clad intersection and perforation zone are described in depth in this experimental study.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"38 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141552150","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}
