Underwater Friction Stir Fabrication and Performance Analysis of AA2024 Composites Reinforced With In Situ AlB2

open access: yesEngineering Reports, Volume 7, Issue 9, September 2025.
Underwater friction stir processing at ˜800 rpm produced AA2024/AlB2 composites with optimum grain refinement (2.3 ± 0.1 μm), hardness (139.5 ± 2.9 HV0.1), and tensile strength (596.4 ± 10.1 MPa). Rotational speed strongly influenced microstructure: low speed (600 rpm) yielded fine but unevenly reinforced grains, while high speeds (1000–1200 rpm ...
