Experimental Verification of Mechanical Properties of SiC Reinforced Aluminium Metal Matrix Composite using Ultrasonic Technique
Main Article Content
Abstract
In this paper, an experimental based investigation of mechanical properties of SiC particles reinforced aluminium metal matrix composite (AMMC) manufactured by liquid metallurgy process has been carried out. The ultrasonic technique has been used for characterisation of material properties by correlating the attenuation of ultrasonic velocity with the amount of particle reinforcements. The amount of SiC particle loading has influenced the ultrasonic velocity at both manufacturing stage and forging test. The material properties like tensile strength, elongation percentage, hardness, wear resistance, impact strength and strength under different forging conditions have been significantly influenced by the weight percentage of SiC particles. The failure of AMMC specimens were characterized through SEM analysis.
