Characteristic study for low melting point MMC using stir casting technique

Abstract

This paper presents manufacturing of metallic composites using stir-casting method. The setup details and manufacturing methodology are explained. Microstructure and characterization of graphite-tin composite is also included. The tensile strength and hardness improvement is observed in tin-graphite MMC with increase in weight percentage of graphite. Metal-matrix composites (MMC's) are now attracting enormous interest. One of the prime reasons for this is that significant advances have been made in recent years on the development of fabrication routes, which are economically attractive and generate material of high micro structural quality. In particular, it is possible to produce composites, which are relatively free from gross defects (Clyne and Mason, 1987; Smith and Froes, 1984; Rodes and Spuurling, 1985; Hunt, 1989; Ted Guo and Tsao, 2000). However, it depends on the ability of synthesizing them with a consistent reproducibility in microstructure and properties. With continual development in fabrication techniques, MMC's have been found to be suitable to replace some of the conventional metallic monolithic alloys.
