Abstract

The effect of structural state after deformation on the corrosion resistance of pure magnesium was studied. It was found that upsetting by ~10% at a temperature of 150°C of the state annealed after equal channel angular pressing (ECAP) allows one to obtain the best corrosion resistance (11.2 ± 0.6 mm/year) by increasing the density of the twins to 779 × 10–5 μm–2.
