| Abstract Scope |
With its superior strength and electrical properties, graphene offers great potential as a reinforcement material in metal matrix composites (MMCs). However, challenges exist in achieving uniform dispersion of graphene during manufacturing. Traditional methods and advanced techniques have limitations in terms of cost and scale of production. Friction-stir based processes are proven energy-efficient techniques that show promising results to achieve homogeneous graphite dispersion. In this research, a friction-stir based novel SolidStir® Extrusion (SSE) technique was used for the in situ synthesis of Al-graphene MMC rods. Key factors driving the exfoliation process that leads to graphite→graphene conversion during SSE were studied by comprehensive characterization techniques such as Raman spectroscopy and TEM. A constitutive Raman analysis revealed that SSE led to the exfoliation of graphite into multilayered graphene. Furthermore, mechanical property characterization and electrical conductivity (EC) tests conducted on SSE-processed Al-graphene MMC rods demonstrated a favorable synergy between strength and EC. |
