چکیده مقاله:
In this study a novel strategy was developed via flake powder metallurgy followed by slurry blending combined with rheocasting and hot-extrusion processes to prepare hybrid AA۷۰۷۵-matrix composite reinforced with CNTs+GNPs. No Al۴C۳ phase was detected in Raman spectrums. In the extrudedCNTs+GNPs/AA۷۰۷۵ composite, plate precipitates were predominant and some lath-like dynamic precipitates were observed at the GNPs/AA۷۰۷۵ interfaces. The intensity of texture in all pole figures was stronger in the CNTs+GNPs/AA۷۰۷۵ composite with respect to AA۷۰۷۵ alloy
