The processing of nitinol via L-PBF, however presents a challenge as it results in an inhomogeneous microstructure that affects mechanical performance and can limit functional property performance. Moreover, an understanding of Ti-rich NiTi processed via L-PBF is lacking. Post-processing heat treatments are an avenue to alter and tailor the microstructure and thus influence the resulting phase transformations and mechanical performance. This paper presents various heat treatments and the influence of their resultant microstructures, phases and transformation temperature behaviour is characterised.FulltextenNitinol (NiTi)Laser Powder Bed FusionPost-processing heat treatmentArticlen/a
