Application of sefere plastic deformation methods in powder metalurgy can make the production of bulk materials from powder possible on lower temperatures than conventional methods. Having lower process temperature means less energy consumption for the process. Except for the lower energy consumption, using severe plastic deformation methods can increase some of mechanical properties like strenght, hardness and yield strenght while elongation decreases in relation to casted ingots. Another advantage of this processes is fine grain microstructure. Consolidation of pure aluminium powder using BP-ECAP process is considered in this article. Cold isostatic compacted samples are pushed trough the ECAP tool with two square cross section 12 mm x 12 mm x 12 mm channels that intersect in 90°angle. Compacted samples had hardness of 37 HV0,2 and density of 2,394 g/cm3 which makes 89 % of teoretical density of aluminium with average grain size of 90 μm. Samples were pushed with main plunger speed of 8 mm/min at 100°C. Backpreassure plunger was opposing to motion with 87 MPa over 144 mm2 area. Because of the poor tool tolerances, there were a lot of friction between the mold and the insert that goes in front of the backpreassure plunger which contributed to the increased backpreassure and the tool failure. After BP-ECAP consolidation, samples microstructure was directed in longitudinal section and non directed in cross section. In longitudinal section, average grain lenght was 175 μm and average grain width was 54 μm which makes 3,2:1 lenght to width ratio. Average grain size in cross section was 79 μm. After BP-ECAP consolidation, sample had a density of 2,517 g/cm3 which is 93,2% of teoretical aluminium density and hardness of 49 HV0,2.
