Paragraph starter

Friction Stir Welding (FSW) has been identified as a promising solid-state joining process for Aluminium Matrix Composites (AMCs), offering good control over microstructure and mechanical properties. However, the presence of reinforcing materials within the aluminium matrix can lead to accelerated wear of FSW tools, a factor that must be considered in the production phase.
