New insights on the laser powder bed fusion processing of a NiTi alloy and the role of dynamic restoration mechanisms

NiTi alloys are a remarkable class of materials capable of exhibiting unique behaviors such as shape memory effect and superelasticity. Laser powder bed fusion (L-PBF), as one of the most prominent additive manufacturing processes, has been recently used by many researchers to fabricate high-quality NiTi alloys with desired properties. In this research, those findings were exploited to utilize an optimum range of volumetric energy density to …
