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.}, keywords = {J (WoSType)}, cin = {IEK-1}, ddc = {620}, cid = {I:(DE-Juel1)IEK-1-20101013}, pnm = {Rationelle Energieumwandlung}, pid = {G:(DE-Juel1)FUEK402}, shelfmark = {Materials Science, Multidisciplinary}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000291225400008}, doi = {10.1007/s11665-011-9854-y}, url = {https://juser.fz-juelich.de/record/15657}, }
