Feature Selection: An Empirical Study

This study investigates the utilization of waste steel chips as reinforcement in aluminum-based composites through the stir casting technique. Steel chip particles were introduced gradually into the molten aluminum alloy while stirring at 400 rpm for 10 minutes to ensure uniform dispersion. Precise temperature control prevented premature solidification, facilitating effective incorporation of steel chips. The resulting composite exhibited a predominantly uniform distribution of reinforcement, indicating successful processing.The addition of 7.5% waste steel chips led to remarkable improvements in mechanical properties. Tensile strength increased by 15.67%, while hardness showed a substantial enhancement of 25.56% compared to the base composite. Moreover, wear resistance exhibited a notable improvement of 19.45%. These enhancements underscore the efficacy of waste steel chips as reinforcement, revolutionizing manufacturing practices in aluminum composites. The findings highlight the potential for sustainable and cost-effective approaches to enhance mechanical performance, contributing to advancements in materials engineering and promoting eco-friendly manufacturing practices.

et al. 2024

This study explores the advancement of aluminum-based composite manufacturing by leveraging tungsten carbide (WC) reinforcement through the stir casting technique. Aluminum alloy served as the matrix material, enriched with ceramic reinforcement particles. The alloy underwent complete melting in a muffle furnace, maintaining a temperature of about 700°C. Ceramic particles were methodically introduced into the molten alloy, ensuring homogeneous dispersion through continuous stirring at 400 rpm for 10 minutes. The resulting composite exhibited a uniform distribution of WC particles, seamlessly integrated throughout the alloy matrix. Remarkably, the addition of 7% WC reinforcement led to substantial enhancements in mechanical properties: a 22.67% improvement in tensile strength, a remarkable 37.9% increase in hardness, a notable 25.80% enhancement in fatigue strength, and a significant 27.67% improvement in wear resistance. These findings underscore the efficacy of the stir casting technique in optimizing the properties of aluminum-based composites, offering promising avenues for the development of high-performance materials for diverse engineering applications.
