Exploring tribo-mechanical behavior of B₄C Reinforced LM25 aluminum matrix composites for structural applications (opens in new tab)

This study reports a comprehensive evaluation of the impact on the mechanical and tribological properties of boron carbide (B4C) particles reinforced with aluminum (LM25) metal matrix composites (MMCs). The synthesis of four different MMCs using the stir casting method and modifying 3, 6, and 9 wt% of 50 μm B4C particulates ensured the reliability of the results. Tensile strength and hardness increased with the rise in B₄C content. 9 wt% B₄C particulates to the LM25 matrix enhanced the hardne...
