Friction Stir Welding: A Comprehensive Review of Non-Metallic Particle Reinforcement in JointsPages 207-219
S. Suresh Abstract:
Friction Stir Welding (FSW), a solid-state joining technique, has demonstrated superior efficiency in welding metal-matrix-reinforced composite joints. FSW has garnered significant attention in recent years as a viable technique for joining similar and dissimilar materials, particularly those reinforced with non-metallic particles. By utilizing diverse mixture of reinforcement particles and base matrices, FSW outperforms traditional fusion joining methods in terms of effectiveness and reliability. Despite significant progress, challenges persist in achieving a homogeneous distribution of Non-metallic particles in the weld zone, which directly impacts macrostructural and microstructural characteristics. Moreover, the mechanical properties of these welds are intricately linked to process parameters, influencing grain enhancement and reinforcement particle distribution. This review critically evaluates these aspects, providing insights into the current understanding and highlighting areas for future research. Keywords: FSW, Non-Metalic Particles, SiC, Al2O3.
