. . . "Methods of severe plastic deformation of ductile metals and alloys offer the possibility of processing engineering materials to very high strength with good ductility. After typical amount of processing strain a material with submicron grain size is obtained with boundaries of rather low misorientation angles and grains containing a high density of dislocations. In the present study an Al?Mg?Si (EN AW 6082) alloy was severely plastically deformed by equal channel angular pressing (ECAP) to produce such a material. Aluminium alloy prepared in three different initial states of structure was processed by the ECAP deformation technique at room and increased temperature in two different modes. Substructure and grain refinement of specimens were investigated by TEM of thin foils after successive application of different passes corresponding to a different effective true strain. Hardness and tensile measurements were used to observe the evaluation of mechanical properties. Structure stability and changes in mechanical properties related to the applied strain were studied at two elevated temperatures 270 and 350 \u00B0C. The effect of annealing was monitored by structural changes and hardness measurements at different time holds (hours) and even at shorter exposition time of 10 and 20 minutes."@en .
