      abstract     = {Highly porous NiTi alloys with pseudoelastic properties are
                      attractive candidates for biomedical implants, energy
                      absorbers, or damping elements. Recently, a new method was
                      developed for net-shape manufacturing of such alloys
                      combining metal injection molding with the application of
                      suitable space-holder materials. A comprehensive study of
                      mechanical properties was conducted on samples with a
                      porosity of $51\%$ and a pore size in the range of 300-500
                      mu m. At low deformations < $6\%,$ fully pronounced
                      pseudoelasticity was found. Even at higher strains, a shape
                      recovery of maximum $6\%$ took place, on which the onset of
                      irreversible plastic deformation was superposed. Results of
                      static compression tests were also used to calculate the
                      energy-absorbing capacity. Fatigue of porous NiTi was
                      investigated by cyclic loading up to 230,000 stress
                      reversals. The failure mechanisms responsible for a
                      reduction of shape recovery after an increased number of
                      load cycles are discussed.},
