This study presents the shape memory behavior of as-fabricated and solution annealed Ni 50.8 Ti 49.2 alloys fabricated using theselective laser melting (SLM) technique. Results were compared to the initial ingot that was used to fabricate powders. Optical microscopy was employed to reveal the microstructure. The shape memory effect under constant compressive stress and isothermal compressive stress cycling tests wereutilized to investigate the shape memory characteristics of theinitial ingot and fabricated alloys. It wasrevealed that theSLM method and post heat treatments can be used to tailor the microstructure and shape memory response. Partial superelasticity was observed after theSLM process. Solutionizing the fabricated samples increasedthe strength andimproved thesuperelasticity but slightly decreasedthe recoverable strain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
