Microstructures and Mechanical Properties of 6082 aluminium alloy produced by equal channel angular pressing

Popis výsledku v původním jazyce

Microstructure and texture development of the 6082 aluminium alloy during equal channel angular pressing (ECAP) was investigated and correlated with its mechanical properties. The microstructure was effectively refined by ECAP, and the original fiber texture of the extruded 6082 alloy was disintegrated and a new texture was gradually developed by repetitive ECAP pressing. After 6 ECAP passes following the route Bc, the yield stress is lower than for the as-extruded 6082 alloy, indicating that the texture softening is dominant over the strengthening due to grain refinement. Cross-section of original samples was 10 x l0 mm and their length was 45 mm. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was determined approximately. Analysis of structure was made with use of light microscopy and SEM. Mechanical properties of samples after extrusion were determined by tensile test and by so called penetration test.
