Processing and Characterization of AlCu Aluminium Alloys by the ECAE Method

Abstract:

Equal channel angular extrusion method (ECAE) was used to deform AlCu alloys in the range of true strains ε = 1.15 – 2.3. Samples for investigation were produced from extruded bars, conventionally manufactured and from a consolidated powder ingot. The influence of the strain on the structure was studied by using light microscopy and TEM and on properties by hardness measurement. Increased strain caused structural refinement of structure and increased hardness. The structure revealed the presence of the mutually crossing microbands, visible against the background of a high density of dislocations. After annealing, nearly equiaxed grains were formed. The material prepared by powder consolidation possessed greater hardness. The results revealed differences in structure and properties of nominally the same alloy, but processed differently, when subjected to deformation by ECAE
