a Tensile stress-strain curves. b Comparison of tensile fracture stress and total elongation between our specimens and reported superelastic L-PBF NiTi in the superelastic state22,23,24,25. Standard deviations derived from three repeated measurements are so small that the corresponding error bars are obscured by the data markers. c, d Tensile superelastic curves over ten cycles for as-aged and as-fabricated specimens, respectively. e Attenuation of superelastic strain as a function of cycling number. f Comparison of tensile superelastic strain and total elongation between our specimens and reported superelastic L-PBF NiTi specimens22,23,24,25,26,27. The superelastic strain in this study is extracted from the 10th superelastic cycle, whereas the literature data are the values from the first cycle. Standard deviations are smaller than the size of the symbols and thus not visible in the plot.
