| description | Determining material flow patterns during Friction Stir Processing (FSP) of composite substrates poses significant challenges in achieving a uniform distribution of reinforcement particles. This article investigates the effects of tool rotational speed (RS) and traverse speed (TS) on the distribution of these reinforcing particles throughout the FSP process. To assess how process speed—encompassing both rotational and traverse components—affects material flow, particle distribution, temperature, and strain, the study employs the Coupled Eulerian-Lagrangian (CEL) modeling technique. Tracer particles were utilized as a methodological approach to examine the flow of material throughout the FSP. The results indicate that at an RS of 1200 rpm, particle distribution is notably uniform at traverse speeds of 8 mm/min and 32 mm/min. However, when the TS is increased to 80 mm/min, the particle distribution becomes inadequate. In comparison, samples produced at 800 rpm exhibit poorer particle distribution than those fabricated at 1200 rpm. Moreover, the results show that the area over which particles are distributed decreases with higher TS or lower RS. Additionally, the lower RS of 800 rpm generates less frictional heat than 1200 rpm. As the TS increases from 8 mm/min to 80 mm/min, the temperature experienced by the samples also decreases. Ultimately, the maximum hardness is achieved in samples fabricated at 1200 rpm with a TS of 32 mm/min. |
