Investigation of the Feasibility to Process NiTi Alloys with Powder Bed Fusion for Potential Applications
摘要
NiTi is a versatile material with a broad range of functional properties such as shape memory effect and superelasticity in combination with high internal damping capabilities and biocompatibility. Processing NiTi with powder bed fusion for metals (PBF-LB/M) enables new potential to solve engineering problems. Due to the layerwise manufacturing technique associated with additive manufacturing, complex shaped geometries can be realized, which are not possible with conventional manufacturing methods. Hence, the combination of functional material characteristics with powder bed fusion has high potential for novel applications and complex structures. In this work, potential and performance of manufacturing complex NiTi structures is demonstrated.
