In order to improve the properties of aluminum and its alloys, some various approaches (e.g. reduction of grain size, addition of alloying elements and composite manufacturing) have been considered. Among all these processes, the use of solid-state processes such as the friction stir processing (FSP) is highly convenient to create surface composites at temperatures below the melting point. Ther...

The effects of the post-deformation annealing on microstructural evolution hot rolled Al7075 matrix composites reinforced with CNTs and GNPs were investigated. multi-pass rolling was applied stir cast samples. Annealing then to at 450 °C for 4 h. Microstructural examined by SEM, EDS, EBSD techniques. data showed that addition 0.87 vol.% (GNPs + CNTs) significantly inhibited occurrence recrystal...
