The experimental investigation of thermal conductivity of aluminum metal matrix composites

Abstract

Aluminum and its alloys have grown in popularity as steel and other comparable material substitutes. These alloys have exceptional mechanical characteristics. Understanding the thermal behavior of hybrid metal matrix composites is critical in a variety of applications. Metal Matrix Composites' (MMCs') heat conductivity is one of its primary advantages. Because MMCs are utilized in a broad variety of temperatures, it is critical to examine their thermal characteristics at various temperatures in order to understand their behavior. Thermodynamic characterization of composite materials has received a lot of attention and has evolved into a crucial element of materials research and engineering. The thermal conductivity of aluminum alloys with Sic and Gr hybrid metal matrix composites is investigated in this work. Sic (0%, 1.26%, 2.6%, and 3.76%) and Gr (0%, 1.26%, 2.6%, and 3.76%) reinforcements are employed in various weight fractions. A variety of casting processes is used to create the composites, which have an Al-based matrix reinforced with Sic and Gr particles. Casting processes include advantages such as decreased material waste and lower porosity levels. The goal of this study is to examine the thermal conductivity behavior of hybrid composites reinforced with varied weight fractions, particularly at lower weight fractions.
