| Abstract Scope |
Shape memory alloys (SMA), such as Ni-Ti, gained a lot of attention since they are known as promising candidates for actuation and damping applications. However, processing and material costs of Ni-based SMAs often limit wide spread applications. Fe-based SMAs systems gained increasing interest due to cost-efficient processing and lower material costs. However, these alloy systems often suffer increased irreversibility and functional instability upon cyclic loading. Functional irreversibility and early fracture is often related to inappropriate microstructures in polycrystalline material conditions, i.e. a weak texture and large grain sizes. Additive manufacturing (AM) processes may help to overcome this issue, since they allow for direct microstructure design. Thus, the present study focuses on the possibility of microstructure design in FeNiCoAlTiB SMAs using different AM processes. The impact of process induced defects and the microstructure evolution on the functional properties is discussed in view of the applied processing parameters. |
