Abstract

Aluminium-based metal matrix composites (AMMCs) are the most commonly used MMC in the automotive and aerospace applications, because of its special properties. The better way to produce MMCs is stir casting method. In the solid-liquid mixing vessel, a remarkable effect on the particle distribution is its flow behaviour of the fluid. Therefore to lead the experimental research, simulation analysis is a powerful tool. The complexity of obtaining a uniform mixture is an important obligation in the method of stir casting. The advantage of obtaining equal dispensation inside the matrix is a serious issue that affects the features and nature of the integrated materials. The dispensation of the reinforcing particles inside the matrix is dependent on numerous parameters at the time of casting. Crucible particle distribution that is stirred during stir casting was simulated in this work using ANSYS and validation was done based on the value of suspension quality. The effects of some important stirring process parameters such as impeller blade angle and stirrer speed of the molten matrix were examined to get the better particle distribution. AA7068 was used as the matrix and vanadium carbide (VC) and boron carbide(B4C) were used as the reinforcements.
