Texture evolution during room temperature ageing of silver processed by equal-channel angular pressing

The evolution of texture was investigated using silver samples processed by equal-channel angular pressing for different numbers of passes and stored at room temperature for up to 4 months. For 1 and 4 passes, only a slight texture intensity change was detected during storage. For 8 and 16 passes, there was a weakening of components A2θ∗ and Cθ and the development of a strong A1θ∗ component due to significant recrystallization in the severely deformed samples.

Research highlights
► Texture evolution during room temperature storage of ECAP processed Ag.
► Texture changes are stronger for the samples processed through larger numbers of ECAP passes.
► Texture evolution becomes essentially saturated after 3 months of storage.
