The paper reports on preliminary results of microstructural study of Cu-2wt.%Co alloy processed by ECAP. The experimental alloy was cast and annealed at 1273 K for 10 hours followed by water cooling, resulting in the solid solution (the initial state). Further heat treatment was then applied to produce two-phase material with fine distribution of precipitates. ECAP was then conducted at room temperature on both the initial and the precipitation hardened states. Resulting microstructures were studied and characterized by microhardness testing, TEM observations and texture analysis by means of electron backscatter diffraction (EBSD) technique in SEM.
