Spatial characteristics of nickel-titanium shape memory alloy fabricated by continuous directed energy deposition

null null Additive manufacturing has been adopted to process nickel‑titanium shape memory alloys due to its advantages of flexibility and minimal defects. The current layer-by-layer method is accompanied by a complex temperature history, which is not beneficial to the final characteristics of shape memory alloys. In this study, a continuous directed energy deposition method has been proposed to improve microstructure uniformity. The spatial...
