A research team from Shandong University found that laser powder bed fusion (PBF-LB/M) not only serves as a shaping tool for complex structures but also as a metallurgical method to control the phase transformation temperatures and functional properties of NiTi shape memory alloys. By adjusting process parameters like scanning speed, the austenite transformation peak temperature of samples made from the same powder can be tuned across a wide range from 244 K to 316 K, a span of 72 K, while maintaining relative density above 99.5%. Accordingly, the samples exhibit a functional transition from shape memory effect to superelasticity at room temperature, with platform stress tunable between 159 and 416 MPa. Functionally graded NiTi samples fabricated with spatially varying process parameters display multiple stress plateaus and stepwise actuation behavior; their functional stability is further improved after solution and aging heat treatment. The study also successfully fabricated a honeycomb structure exhibiting triple-stage shape recovery behavior.
