520 _ _ |a Powder metallurgy is an attractive production method for complex-shaped NiTi parts. Pre-alloyed NiTi powders are preferred as a starting material for achieving an essentially one-phase homogeneous structure. This work describes in detail how complex-shaped components with fully expressed shape memory properties can be produced from pre-alloyed NiTi powders by means of P/M technologies. The metal injection moulding (MIM) technique was chosen for near-net-shape forming. Simple-shaped components were also produced by hot isostatic pressing (HIP) as a reference. Considering the basic principles of the shape memory effect, this paper provides a detailed description of the process technology factors to be considered for obtaining components with reproducible mechanical properties and fully expressed shape memory properties. Three case studies illustrate the potential of powder metallurgy for processing shape memory alloys: a biomedical foot staple for stabilizing toe fractures, clamping sleeves for domestic engineering and highly porous NiTi components for implants and damping applications.
