Anotace
At present, the equal-channel angular pressing (ECAP) is the most developed of all potential severe plastic deformation (SPD) techniques for achieving very significant grain refinement in metallic materials. Despite enormous research effort in ECAPed materials so far only very limited investigations on the link between their microstructure and creep behaviour have been carried out. Thus, this project is initiated to provide detailed examination of the effect of precipitates on the microstructural stability and creep resistance of the selected precipitate strengthened aluminium and copper based alloys processed by SPD, mostly ECAP. The results should develop optimum processing schemes for attaining the desired creep properties of SPD processed materials.
