Equal channel angular pressing (ECAP) of high-strength aluminium alloys is characterized by the formation of very heterogeneous microstructures that exhibit shear bands on different length scales. This type of inhomogeneous deformation considerably reduces the achievable degree of deformation of high-strength materials during ECAP. In this project, the fundamental microstructural processes are studied by microstructural and mechanical characterization, and they are correlated with the macroscopic material behavior.
