ABSTRACT In the present study, aluminium sheets were produced through the hot rolling of Spark-Plasma-Sintered (SPSed) discs. The effects of post possessing on the microstructure, texture and mechanical properties of the SPSed and hot-rolled specimens were studied using SEM-EBSD, tensile and microhardness tests. It has been shown that the hot-rolled specimens depict finer and equiaxed microstructure if compared with the SPSed ones. In addition, tensile properties improved in the hot-rolled specimens if compared with those belonging to the SPSed materials. This behaviour was attributed to porosity reduction, dynamic recrystallisation phenomena, grain refinement and formation of new grain boundaries. Although S {123} <634> was the main texture component in SPSed sample. Cube component {011} <211> formed after hot rolling.
