Notes:
Pure commercial Cu of 99,98 wt % purity was processed at room temperature by Equal-Channel Angular Pressing (ECAP) following route Bc. Heavy deformation was introduced in thesamples after a considerable number of ECAP passes, namely 1, 4, 8, 12 and 16. A significant grainrefinement was observed by transmission electron microscopy (TEM). Tensile and microhardnesstests were also carried out on the deformed material in order to correlate microstructure andmechanical properties. Microhardness measurements displayed a quite homogeneous straindistribution. The most significative microstructural and mechanical changes were introduced in thefirst ECAP pass although a gradual increment in strength and a slight further grain refinement wasnoticed in the consecutive ECAP passes
