Influence of structural state on mechanical properties of pure titanium and magnesium alloy WE43 as candidates for use as nondegradable (titanium) and degradable (WE43) medical implants was studied. By the methods of severe plastic deformation in combination with programmed heat treatment the nanostructured pure titanium and ultra-fine-grained magnesium alloy WE43 were obtained. It is shown, that grain size substantially affects not only the mechanical properties of the indicated materials but also the corrosion rate of magnesium alloy WE43 in the medium simulating biological fluid. The possibility of replacing the titanium implants by nanostructured pure titanium and future application of degradable ultra-finegrained magnesium implants is discussed
