Characteristics Enhancement of Mechanical Properties of Aluminum Metal Matrix Composites Reinforced with Silicon Carbide Using Stir Casting Technique

Metal Matrix Composites (MMC) made of the aluminium as base metal is now being used in diversed applications due to its extended properties. The physical, chemical, mechanical and structural properties make it as irresistible in the engineering applications. Metal Matrix Composites (MMCs) based on aluminium have increased in popular in various applications including aerospace, car, space, transportation, and undersea applications.. In this study, Al LM25/SiCp MMC was fabricated using a low-cost stir casting technique, and the weight percentage of SiCp was varied from 4% to 8% to prepare the MMC plates. The aim of the research was to investigate the mechanical properties of the specimen, including hardness, tensile, and impact tests. The microstructure of the specimens is investigated which shows the bonding between the particles which is fabricated by Stir casting method. The sample 2 has better mechanical properties when it is compared with other specimens. With the increase in the addition of SiC the elongation of the specimen getting higher. The composite materials is expected to be involved in the fabrication of automotive components.
