Abstract
Equal channel angular pressing (ECAP) was performed on extruded pure Mg, which was clad with a drilled pure Fe coat through an ECAP die to produce a pure Mg sample without obvious cracks at room temperature. After one-pass ECAP, the grain size decreased because of basal slip activation during the dynamic plastic deformation but the microstructure became inhomogeneous. The deformed texture was less scattered and inclined by ~20° from the normal direction toward the extruded direction, and low angle boundaries increased continuously. The mechanical properties decreased slightly as a result of the combined effect from a more refined microstructure and a weaker texture.
