| 520 | _ | _ | |a 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. All rights reserved. |
