Evolution of texture during hot rolling of aluminum borate whisker-reinforced 6061 aluminum alloy composite

The textures and microstructures of hot-rolled aluminum borate whisker-reinforced 6061 aluminum alloy composites with different reductions have been investigated. Compared with the typical rolling textures for monolithic aluminum alloys, different hot-rolling textures were found in the matrix of the composites. New plate textures are dominant for the specimens with 30% and 50% reductions, and fiber textures for the specimen with 70% reduction. The increasing reduction transforms some plate textures into fiber textures, and develops the original fiber textures. Furthermore, some typical rolling and recrystallization texture components for monolithic aluminum alloys with low orientation distribution densities can be observed in the composites with 50% and 70% reductions.
