Abstract: Stir casting is an appealing processing method for manufacturing MMCs among the various composite materials processing methods. It is reasonably priced and provides a diverse range of materials and processing options. The stir casting method includes introducing pre-treated or warmed ceramic particles into the spinning impeller's molten alloy vortex. In this technique, the distribution of the reinforcement material in the matrix should be homogeneous, and the wet ability between the molten matrix and reinforcement particles should be adjusted in order to produce the best characteristics of the metal matrix composite. This technique may achieve appropriate integration by carefully selecting process parameters such as pouring temperature, stirring speed, reinforcement preheating temperature, carrier gas usage, and so on. Controlling usually undesired characteristics such as porosity caused by gas entrapment during mixing and oxide inclusions is critical to the effectiveness of stir casting. The current research focuses on the design of various forms of mechanical stirrers and their effects on vortex generation and dispersion, as well as the usage of a carrier gas such as Argon.
