Friction stir welding (FSW) is employed for of aluminium metal matrix composite (MMC) reinforced with zirconium dioxide and Graphite as the reinforcing element. Stir casting used mixing MMC The specimens are fabricated in form rectangular plates then welded using FSW process. process parameters considered this work are; tool rotational speed, speed axial load. tensile strength hardness weld nug...

A three-dimensional numerical model is used to simulate the Friction Stir Welding (FSW) process using the computational fluid dynamics package ‘FLUENT’. Two mechanical models: the Couette and the Visco-Plastic fluid flow models for Al-6061-T6 were simulated. The simulation results are compared to experimental data for Al 6061-T6 welded at high rotational (1500–5000 rpm) and travel speeds rangin...

Metal matrix composites (MMCs) exhibit improved strength but suffer from low ductility. Metal particles reinforcement can be an alternative to retain the ductility in MMCs (Bauri and Yadav, 2010; Thakur and Gupta, 2007) [1,2]. However, processing such composites by conventional routes is difficult. The data presented here relates to friction stir processing (FSP) that was used to process metal ...

The aim of the present research is to investigate the fatigue behaviour of friction stir (FS) welded tubular joints in aluminium alloy subjected to torsional fatigue loading. To manufacture the samples which were tested, an MTS I-STIR process development system was equipped with a retracting tool specifically designed for these tubular welds. Al 6082-T6 FS welded samples were tested under cycli...

In this study, 5052 Al–Mg alloy was pre-treated and friction stir processing (FSP) was then performed on the specimens to explore the deformation resistance. The experimental results indicate that the FSP specimens not only had better tensile properties but also better vibration fracture resistance. It is significant that the tensile elongation and deformation resistance tended to increase as t...

Abstract In the current investigation, influence of post-process and in-process cooling on microstructural, mechanical electrochemical behavior wide-area stir zone (WSZ) processed with overlapping friction processing (OL-FSP) was studied. The WSZ successfully prepared in Al5083 aluminum alloy using multi-pass (FSP) 50% pin under both conditions. FSP (PP-FSP) used solid CO 2 as media, whereas (I...

The Friction Stir Welding (FSW) process depends entirely upon mechanical contact between the tool and workpiece. As a result of this, all phenomena outcomes such as weld geometry properties are governed by FSW’s frictional system. following work characterizes this system with focus on initialization, heat input material flow. For purpose, an experimental program for isolated investigation was c...

In this research, St37 and 316L steel sheets were welded using friction stir welding (FSW) process and effective parameters such as the rotational speed, linear speed of the tool, pin diameter, and their appropriate values were studied. The microstructure, hardness, and strength of the different welding regions were investigated. It was observed that in the stir zone (SZ), a mechanical operatio...
