| Abstract Scope |
Shape memory alloys (SMA), such as Ni-Ti-based SMAs, gained a lot of attention since they are known as promising candidates for actuation and damping applications. Additions with Hf are known to increase the transformation temperatures and, thus, the temperature range for application. However, significant additions of Hf result in an increase of brittleness, limiting the thermomechanical processing window. Additive manufacturing (AM) processes may help to overcome this issue, since these processes allow for manufacturing of near-net shaped functional materials. The present study focuses on a Ni-Ti-Hf SMA processed via powder bed fusion processes. The impact of process induced defects on the functional properties is discussed in view of the chemical composition and microstructural findings. |
