abstract = {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.},
