“…Mazaheri et al, investigated the influence of traverse speed on microstructure and mechanical properties while modifying copper alloy via friction stir processing. Results portrayed a reduction in grain size and increase in micro hardness value with respect to increase in traverse speed [26]. Naik et al, fabricated copper -tungsten surface composites via friction stir processing and analyzed the effect of different traverse speed on the mechanical properties of the developed surface composites.…”

This research deals with investigating the effects of amount of hybrid reinforcement, rotational speed and traverse speed on the mechanical and wear characteristics of copper surface composites fabricated via friction stir processing. Aluminum oxide and boron carbide at 1:1 ratio was dispersed onto copper substrate at various volume fractions (5, 10 and 15 vol. %) at different traverse speed (40, 60 and 80 mm/min) and rotational speed (800, 950 and 1300 rpm). Microstructural characterization of developed copper surface composites dispersed with varying volume fraction of hybrid reinforcement proved reduction in grain size and homogenous distribution of ceramic particles. Results stated that the percentage of particles dispersed, traverse speed and rotational speed have high impact in defining the property of developed copper surface composites. A positive trend in mechanical strength was observed throughout the study. Increase in hybrid reinforcement dispersion and traverse speed increases the microhardness value of developed surface composites while increase in rotational speed leads to reduction in microhardness value.

This study evaluates the impact of cooling-assist friction stir welding (CA-FSW) tool rotational and traverse velocities on the bonding quality of Al-Cu-Mg and copper lap joints. A modified computational fluid dynamics (CFD) technique analyzes heat generation and distribution during dissimilar CA-FSW joints between AA6068 alloy and copper. The relationship between CA-FSW tool velocities and metallurgical properties of the final joint is assessed. Simulation results provide insights into metallurgical phenomena during the CA-FSW process. Findings reveal greater plastic deformation and heat generation on the AA6068 aluminum alloy side due to raw material placement, resulting in more significant microstructure changes in AA6068 aluminum alloy compared to copper. Increased heat generation leads to higher copper-rich intermetallic compound (IMC) formation, resulting in increased hardness of the stir zone at the base metals’ interface.

Friction stir processing (FSP) stands as an effective approach designed for grain refinement and site-specific microstructural modification. The evolving microstructure during FSP is determined by various variables out of which rate of sample cooling is the key parameter. More often, FSP is conducted in naturally flowing air; however, a large number of studies are conducted by researchers across the world; stressing the importance of additional sample cooling strategy for tailoring the material microstructure. Such strategies vary not only in terms of the cooling medium used but also with regard to various other compliant conditions that must be fulfilled for the cooling process to make them successful and economically viable. This work critically reviews the most prevalent methods practiced by various researchers and industries for controlled sample cooling during and after FSP. The underlying mechanisms; advantages; disadvantages; and limitations of each procedure along with the resulting microstructure and material performances are discussed and recommendations are provided
