Abstract
This article presents the physical and metallurgical parameters, which affect the distribution of the discontinuous reinforcements in the matrix of metals or alloys fabricated by liquid state processing. The metal matrix composites (MMC) were developed using stir casting at a speed of 800 rpm, the temperature of 750 °C using a pitched blade stirrer. The strengthening mechanisms have been predicted using the classical continuum model and the factors affecting the load and stress distribution are discussed explicitly. For the prediction of elastic properties, two simple limiting models of the rule of mixtures are generally used. The rule of the mixture has been found most appropriate for the composites with continuous reinforcements. The iso-stress condition has given lesser error in the elastic modulus. In presence of the deformable particles, the composite may undergo extensive plastic deformation. The mathematical models and the empirical relationships suggested in this article will help the researchers and industries to design the discontinuously reinforced composite materials and to control the reinforcement distribution and matrix strengthening.
