Four aluminum nanocomposites were produced using cold and hot pressing at 560 °C for 50 min under 1000 MPa. Raman analysis confirmed graphite exfoliation with alumina to graphene after 40 h of milling. The hot-pressed aluminum-5(alumina/graphene)/10 silver exhibited the smallest crystallite size at 79.926 nm and the highest hardness at 61 HV. It also demonstrated the lowest wear rate under different applied loads (45 and 90 N). The coefficient of friction was measured under 90 N, revealing the lowest mean coefficient of friction of 0.5 for aluminum-5(alumina/graphene)/10 silver, attributed to the presence of graphene and silver as solid lubricants. Aluminum/(alumina/graphene) showed superior corrosion resistance in the absence of silver, reducing the corrosion rate from 0.01 mm/year for pure aluminum to 0.0073 mm/year with the addition of 5 (alumina/graphene).

Furthermore, the mechanical properties of aluminum alloys can be enhanced further through their utilization in the fabrication of metal matrix composites (MMCs). In contemporary times, friction stir processing (FSP) is increasingly employed as a surface modification technique. FSP enhances the surface properties of materials by subjecting them to severe plastic deformation, mixing, and fragmentation of the base material through the spinning action of a rotating tool, coupled with the heat generated by friction. This paper provides a thorough examination of the research conducted in the realm of friction stir welding (FSW) and friction stir processing involving the aluminium alloys with nanoparticles reinforcement and also the strategies involved during reinforcement. It scrutinizes the effects of reinforced nanoparticles on processing parameters, explores the formation of microstructures, and assesses the resulting mechanical properties.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"39 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206268","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 influence of welding parameters on welding quality and strength was assessed by varying rotational speeds and traverse speeds, the optimal welding conditions. Welded samples with a cross section of 28 mm and excellent surface smoothness were prepared and analyzed to measure the residual stress using X-ray diffraction (XRD) techniques. This study investigated the effect of tool geometry and type on residual stresses in welded specimens and highlighted the importance of choosing the appropriate tool geometry and type to minimize residual stresses. Furthermore, finite element simulation of the FSW process was conducted using a thermal modeling approach to calculate the heat generated and predict residual stresses using ABAQUS software. Comparison of the residual stress values obtained from numerical simulations with experimental measurements demonstrated the model’s ability to predict residual stresses in FSW adequately. The experimental and numerical results revealed that an increase in rotational speed and tool feeding led to higher stresses in the welded region due to an increased thermal gradient. Examination of the microstructure shows that during the welding process, the weld cross-section has become smaller than the base metal. The ultimate tensile strength and microhardness obtained in optimal conditions were 245 MPa and 108.2 HV, respectively. Examining the fracture surfaces from the tensile tests showed the soft fracture type, which is characterized by the presence of holes and depressions in the three-layer sheet.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"1 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226393","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 relationship between the geometrical morphology of the coating cross section and laser process parameters was systematically studied. The influence of line energy and the number of remelting on the morphology of the coating cross section was mainly discussed, and the uniformity of coating elements distribution was regulated by multiple remelting. The coating cross-sectional dimensions, element distribution and hardness values were measured by stereomicroscope, energy-dispersive spectrometer and microhardness tester. The results show that the cladding height of CrMnFeCoNi high-entropy alloy coating increases first and then decreases with the increase of line energy, but the value changes slightly. The cladding width and cladding depth gradually increase with the increase of line energy and remelting times. When the coating is remelted 2 times, there is an incompletely melted island-like CrMnFeCoNi high-entropy alloy powder in the upper left corner of the coating. When remelting 3 times, there is no incompletely melted high-entropy alloy aggregate, and the uniformity of coating is better than that when remelting 2 times. The uniformity of coating composition is the best after 4 remelts, and the hardness of coating reaches 459.67HV0.2 when the line energy is 0.67 J/mm for 4 remelts.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"57 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141932011","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 joints are obtained by robotic pulsed gas metal arc welding in argon (GMA welding) with transverse oscillations of the electrode. The studied macrosections of welded joints of high-temperature nickel alloys show an extremely atypical picture of the fine-grained structure of the WAZ with local grain growth regions, comparing to previous experiments using pulsed GMA welding. The welded joints of the EP718 alloy samples of 4 mm thickness obtained by pulsed GMA welding demonstrated the ultimate tensile strength of 1056 MPa. The short-term strength of welded joints of the EP718 alloy 4 mm thickness at 650 °C reached the value of 949 MPa. According to EDXS analysis, particles of the TixNy type and carbides of the MxCy type are distinguished along the boundaries of such areas. These particles are formed in the WAZ zone in the temperature range of 700–1200 °C. A detailed EDXS analysis of WAZ revealed an increased content of molybdenum and sulfur in certain sections with a simultaneous decreased content of niobium and iron, as well as sections with increased (by 50–70% compared to the initial alloy) concentrations of niobium and molybdenum.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"303 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141932092","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}
