      abstract     = {Porous NiTi alloys are highly attractive for energy
                      absorbers, damping devices and biomedical implants. In the
                      present work, metal injection moulding (MIM) in combination
                      with the application of a suitable space holder material was
                      used for the production of NiTi parts with well defined pore
                      sizes and porosities in the range of 30-70 $vol.\%.$ For
                      comparing the properties, porous titanium and Ti-6Al-4V
                      samples were prepared in the same manner.Focus of the
                      present work was a detailed investigation of the mechanical
                      properties of porous NiTi to estimate its potential
                      regarding the abovementioned applications. For a Ni-rich
                      NiTi alloy with a porosity of 50 $vol.\%,$ fully pronounced
                      pseudoelasticity after $6\%$ compression was demonstrated.
                      An energy dissipation of 1.5 MJ/m(3) was measured, which
                      could be directly related to the reversible
                      austenite-martensite phase transformation. At higher
                      deformations, pseudoelasticity becomes more and more
                      superposed by the onset of plastic deformation.
                      Nevertheless, even at deformations of up to $50\%,$ a
                      clearly pronounced amount of pseudoelastic shape recovery
                      still remained. Fatigue of pseudoelasticity was investigated
                      by conducting of up to 230,000 load cycles to $4\%$
                      compression at a frequency of 1 Hz. (C) 2010 Elsevier B.V.
