Abstract : The incorporation of ceramic particles into magnesium metal matrix composites is garnering significant interest as a novel lightweight material due to its favorable strength-to-weight ratio, vibration-dampening properties, and biocompatibility. These attributes render them ideal for applications where weight is critical, such as components in the aerospace and healthcare sectors. The incorporation of reinforcing particles is a crucial step in altering the aging process of magnesium alloys. After heat treatment, the mechanisms of precipitation alter, the microstructural characteristics improve, and phase transitions occur more rapidly. This work analyzes the impact of various parameters, including reinforcing type, particle size, and volume %, on the aging characteristics of magnesium composites subjected to T4 and T6 treatments. A thorough examination of the essential mechanisms is conducted, including the increased dislocation density due to particle interactions, the enhanced heterogeneous nucleation at the interfaces between particles and the matrix, and the expedited diffusion of solutes. This study scientifically evaluates the modifications to the aging properties of Mg-MMCs designed to improve their mechanical performance, while providing valuable insights for the development of next-generation materials for aerospace, biomedical, and structural applications.
