DOI: 10.1007/s40830-024-00491-z
Abstract: Coupled in situ investigations were conducted on a Fe–Mn–Al–Ni–Ti single crystal deformed in compression and two Fe–Mn–Al–Ni–Ti oligo-crystals deformed in tension. Acoustic emission measurements were employed to monitor the degradation of superelasticity and the stabilization… read more here.

DOI: 10.1016/j.actamat.2016.10.062
Abstract: Abstract Superelasticity in nanoscale materials is of profound fundamental interest. Despite extensive research into low-dimensional systems such as nanowires and nanobeams, no compelling evidence exists for superelasticity in high-dimensional systems. Here, we demonstrate that a… read more here.

DOI: 10.1016/j.scriptamat.2021.114123
Abstract: Abstract We demonstrate excellent superelasticity and giant elastocaloric effect in a directionally solidified Co50.7V33.3Ga16 alloy. Owing to the formation of [001]A preferentially oriented columnar grains, the as-grown alloy displays nearly perfect superelastic behaviors with fully… read more here.
