N2 - This paper marks the first report on the fact that interstitial hydrogen improves the shape recovery property of an Fe-based face-centered cubic alloy, regardless of pre-strain level. The maximum shape recovery strain when using hydrogen was increased from 2.8 to 3.4 pct at an approximately 7 pct pre-strain. The enhancement of the shape memory effect by hydrogen stems from (1) increasing deformation-induced martensite fraction, (2) thinning of martensite plates, and (3) increasing the number of martensite plates.
