The free-standing film showed a pronounced “two-way” shape memory effect (SME). In the austenitic state the film presents a flat shape. During cooling, by reducing its distance from ice cubes (i.e., decreasing the surrounding temperature), the film starts bending exhibiting a final curled shape (yet without touching the ice). On heating it recovers its flat shape. The authors attribute the nature of this “two-way” SME to the Ni4Ti3 precipitates that formed during the heat treatment.}, note = {Martins, R.; Schell, N.; Gordo, P.; Maneira, M.; Silva, R.; Braz Fernandes, F.: Development of sputtered Shape Memory Alloy (SMA) Ni–Ti films for actuation in ice cooled environments. 7th Iberian Vacuum Meeting and the 5th European Topical Conference on Hard Coatings.
