Fatigue behavior of TiNi foams processed by the magnesium space holder technique

► We report on the fatigue behavior of TiNi foams processed by the magnesium space holder technique. ► The endurance limit is independent of the porosity content in the range 49-64 vol.%. ► The mechanical properties of the foams are suitable for biomedical applications. ► Fatigue failure occurs on the pore walls by micro-crack coalescence.
