Metal matrix composites (MMCs) exhibit remarkable properties that make them highly sought-after in various industries, including aerospace, defense, automotive, and engine components that require heat and wear resistance. Among MMCs, aluminum matrix composites (AMCs) are particularly favored, with applications ranging from aerospace and military to everyday consumer products such as sports vehicles and medical equipment. Research and development in the aerospace and defense industries have facilitated advancements in MMC technology. Moreover, the widespread application of MMCs in daily life underscores their versatility and importance in modern engineering. In this context, understanding the fracture behavior of AMCs (such as SiCp/A356, SiCp/AA6061, and Al2O3p/AA6061) in welded joints across various temperatures is crucial. This research aims to provide essential insights into the fracture characteristics of AMCs, contributing to efforts to develop eco-friendly MMCs that reduce environmental impact and waste production. By promoting the development and adoption of green composites with a minimal environmental footprint, this research aims to create new market opportunities and drive sustainable growth in the industry.
