DESIGN AND SIMULATION ON CAST METAL MATRIX COMPOSITE BY INVESTMENT CASTING

Metal Matrix Composite (MMC) is produced normally by melting the matrix material in a vessel and the molten metal is stirred systematically to form a vortex, and then the reinforcement particles are introduced through the side of vortex formed. However, this approach has disadvantages, mainly arisin...
