Study of stirrer speed and preheat temperature on stir cast aluminium matrix composite materials – A review

Abstract Composite materials are new generation materials used in various fields like aerospace, automobile, electronics due to their tailored properties. Most of the composites are prepared by the stir casting technique. So, a detailed study about stir casting parameter like stirrer speed, preheat temperature is needed to identify the effect of these parameters on the properties of composite materials. It has been found that the properties of Aluminium alloy MMC are affected due to the variation in the speed of stirrer and preheat temperature. After reviewing many papers, we find the range of stirrer speed is 150–1300 RPM and preheat temperature 250°C–1100°C is suitable because there is an increase in stirrer speed, uniform distribution of the reinforcement particles, and proper spreading of reinforcements in the matrix and muscular bonding between matrix were obtained. After investigating the newly developed composite by X-ray diffraction (XRD) and Scanning Electron Microscopic (SEM) microstructure method, it has been found that an increase in preheat temperature of reinforced material improves the mechanical property like toughness, wear resistance. This research paper will help the researcher select metal alloy; additive reinforces the material and their size and volume.
