Abstract   NiTi parts have been produced by injection moulding. A feedstock consisting of elemental titanium hydride and nickel powders blended with an organic binder was used. By using scanning electron microscopy observations coupled with an energy-dispersive X-ray analysis it was shown that the parts essentially consist of NiTi except some small Ti-rich domains and a contaminated surface layer. The presence of a martensitic transformation in the temperature range above room temperature was shown by differential scanning calorimetry. Shape memory effects of more than 4% were achieved.
