Microstructure and corrosion behaviour of ultrafine-grained pure magnesium by severe plastic deformation has been investigated in term on initial deformation process as a biodegradable material. Equal channel angular pressing (ECAP) has been chosen as severe plastic deformation which can be introduced into the material without changing the material geometry. The ECAP process was carried out at 523 K. The microstructure was characterized by scanning electron microscope which is equipped by electron backscatter diffraction, and the corrosion behaviour was investigated by electrochemical test. The ECAP processed sample show that the deformation structures has sub boundaries in one pass and a high fraction of high angle grain boundary due to high misorientation in the grain boundaries. The corrosion behaviour exhibited that ECAP processed sample has a lower corrosion rate than that as-annealed sample due to deformed structure.
