Cu-Al-Ni shape memory alloys (SMAs) are currently the only available high temperature SMAs, showing a good resistance against functional fatigue. In polycrystalline state, they are very brittle and exhibit, in general, only small reversible deformations. By melt spinning, thin Cu-Al-Ni ribbons can b ...

This work addresses three topics: the generation of two-way shape memory effects in NiTi, NiTiW and CuAlNi wire materials and the investigation of the long term stability of these effects; investigations on thin CuAlNi films produced by PVD; investigation on thin CuAlNi ribbons produced by melt-spin ...

This work investigates the possibilities for applying a focussed ion beam (FIB) for the metallographic preparation and characterization of Cu-Al-Ni melt-spun ribbons. Two alloys were selected for this reason: CuAl13Ni4 and CuAl15Ni4. The microstructure of the first alloy was fully martensitic and th ...
