TL;DR: In this article, the current status of nanoparticle reinforcement FSW process is analyzed and various properties associated with reinforced joints are presented with the mechanism of the relationship between microstructure and properties.
Abstract: Nanomaterial reinforced friction stir welding (FSW) is an emerging domain, as it delivers a promising method for enhancing joint properties by making composite joints. Composite joints can enhance surface properties like hardness, strength, corrosion resistance, wear resistance, fatigue life, electrical conductance. Over few years many publications have been reported on the application of nanoparticles reinforcement in FSW joints. The present review critically analyses the current status of nanoparticle reinforcement FSW process. Firstly need, type, behaviour, intrinsic properties of nanoparticles used in FSW are discussed. Then, the microstructural examinations of reinforced joints are analysed. Followed by, various properties associated with reinforced joints are presented with the mechanism of the relationship between microstructure and properties. Finally, various methods of deposition of nanoparticle in FSW is discussed. At last prospects of reinforced FSW are explored followed by concluding remarks.

TL;DR: In this article, the effect of adding novel biochar microparticle into the welding zone of dissimilar friction stir welding of AISI-SAE 1010 (steel) and CDA 101 (copper) alloys was investigated.
Abstract: This present work investigates the effect of adding novel biochar microparticle into the welding zone of dissimilar friction stir welding of AISI-SAE 1010 (steel)–CDA 101 (copper) alloys. The primary aim of this work was to produce efficient weld joints in AISI-SAE 1010–CDA 101 alloys using biochar as solid lubricant via friction stir welding process. The biochar particles were prepared from rice husk biomass via carbonization process. The welding was performed using tapered pin profiled tool with rotational speed of 900 rpm, traverse speed of 30 mm/min, axial load of 5 KN, dwell time of 5s, plunging depth of 0.2mm, and biochar additions of 0.5, 1, 2, and 4wt%. The highest tensile strength of 205 MPa, elongation of 44%, yield strength of 177MPa, strain value of 36, and Vickers hardness of 121 were observed for FSW joints made using 2wt% of biochar content. Large addition of biochar up to 4wt% marginally affects the properties. Similarly, the fatigue strength of 157MPa was observed for weld made using 2wt% of biochar. The microstructure of biochar-assisted weld nugget shows highly refined less thermally affected grains. The grains were in equiaxial with distortion-free. The EDAX report confirms the presence of copper, iron, and carbon on the weld nugget, which indicates fine mixing of parent metals with solid lubricant. These mechanical properties improved environmental friendly dissimilar welding method could be used in industrial applications such as automobile, aerospace, construction, defense, medical, energy where high strength with high durable weld joints are required to meet the current technology demand, and process economy.

TL;DR: In this article, aluminum hybrid composites using bamboo leaf ash (BLA) and alumina have been fabricated via stir casting and the effect of the EDM machining process parameters on the output responses such as surface roughness (Ra) and material removal rate (MRR) are evaluated using grey relational analysis.
Abstract: In this research work, aluminum hybrid composites using bamboo leaf ash (BLA) and alumina have been fabricated via stir casting. Three hybrid composites viz: A713 + 2%BLA + 2%Al2O3, A713 + 2%BLA + 4%Al2O3, A713 + 4%BLA + 2%Al2O3 are fabricated successfully and EDM machining of these three composites is performed. The EDM machining experiments of the three hybrid composites, have been designed using Taguchi L27 orthogonal array design of experiments (DOE) considering current (A), duty cycle (%), gap voltage (V) and different percentage composition of the reinforcements. The effect of the EDM machining process parameters on the output responses such as surface roughness (Ra) and material removal rate (MRR) are evaluated using grey relational analysis.

TL;DR: In this paper, the authors investigated the structural, mechanical properties and wear resistance of FSP-processed materials as a function of volume fraction of SiC particles and found that adding micro-and nano-sized particles decreases the tensile strength and percent elongation.
Abstract: In this experiment, copper-base composites reinforced with 30 nm and 5 μm SiC particles are fabricated on the surface of a purecopper sheetvia friction stir processing (FSP). Microstructure, mechanical properties and wear resistance of friction stir processed (FSPed) materials are investigated as a function of volume fraction of SiC particles. Results show that, applying FSP, without SiC particles, increases the percent elongation significantly (more than 2.5 times) and decreases copper's strength. Adding micro- and nano-sized SiC particles decreases the tensile strength and percent elongation. Increasing the volume fraction or decreasing the reinforcing particle size enhances the tensile strength and wear resistance and lowers the percent elongation.
