ECAP Processed Copper during Deformation and Subsequent Annealing
Microstructure and texture evolution of pure copper (99.95%) after Equal-Channel Angular Pressing (ECAP) and subsequent heat treatment were investigated. Initially the material was subjected up to twelve passes with a 90° die angle using route Bc. This resulted in an equivalent strain of 13.8. After deformation the samples were annealed at different temperatures. The deformed and annealed states were characterized by using the crystallographic texture analysis, EBSD measurements and microhardness tests.
