摘要

Friction stir processing (FSP) is a cutting-edge approach for developing composites, improving material mechanical properties, and refining microstructure. Employing innovative Friction Stir Processing (FSP), this study pioneers advancements in composite materials by utilizing Aloe Vera nanopowder as reinforcement in fabricating Aluminium Matrix Composites (AMC) on Al6061 alloy. Variations in tool rotational speeds are explored to optimize material properties. The research delves into the mechanics by measuring forces and torque during processing, establishing correlations between stress distributions on the tool pin and composite quality. Comprehensive analyses including microstructure examination, tensile strength evaluation, microhardness testing, and wear assessments unveil the influence of tool rotation speed on the resultant FSPed composite. The study concludes by identifying the optimal rotation speed necessary for achieving desired particle dispersion within the AMC. In this case, a tool rotational speed of 1500 RPM resulted in a composite with a tensile strength of 366 MPa. This higher strength could be due to optimal grain refinement, better dispersion of reinforcing particles achieved during FSP at that specific speed.
