英文摘要SiC and carbon nanotubes (CNTs) hybrid reinforced aluminum matrix composites offer high strength and high modulus. However, the complexity of their microstructure makes forming these materials challenging. In this study, the deformation coordination behavior and microstructure evolution of a hybrid-reinforced 6092Al composite containing 10 vol% SiC and 0.9 vol% CNTs during hot working were investigated by constructing a strain rate sensitivity index (m) map. The results indicated that the deformation coordination of the composite was highly sensitive to the feedback of deformation parameters. At the deformation temperature of 350 degrees C with the strain rate of 0.1 s_ 1, the composite exhibited the better coordination. However, at 350 degrees C with 0.001 s_ 1and 450 degrees C with 0.001 s_ 1, the rheological uniformity deteriorated, leading to the SiC agglomeration. In addition, transmission kikuchi diffraction (TKD) and transmission electron microscopy (TEM) were used to analyze grain evolution after deformation. It was found that abnormal grain growth occurred at high temperatures with low strain rates (450 degrees C and 0.001 s_ 1). This phenomenon is attributed to the increased stress near the SiC, which aids the grain boundaries in overcoming the pinning limit of CNTs at elevated temperatures. This study has significant implications for the microstructure regulation of hybrid composites during deformation processing.
