Powder metallurgy is promising to produce near net shape components of NiTi. Expensive thermomechanical working and machining of cast alloys can thus be avoided and the high loss of material can be overcome. Especially for the mass-production of small and complex shaped parts Metal Injection Molding (MIM) could be profitable. Reduced elongation at fracture and lacking plastic deformation prevented the application of powder metallurgically produced shape memory parts up to now. Due to a clear reduction of impurity contents and therefore lower amounts of oxyde and carbide phases an improvement of the mechanical properties of NiTi produced by MIM as well as Hot Isostatic Pressing (HIP) starting from prealloyed powder is achieved. This is proved in tensile tests by an extended plateau strain as well as elongations at fracture of up to 17 %. Thus, plastic deformation and non-brittle failure behavior has been demonstrated similarly to cast NiTi materials.
