Abstract: A series of the Ti-Ni-Me (Me: Cu, Co, Zr, Hf, Re) and Cu-Al-Me (Me: Ni, Mn, Ti, Nb) rapidly solidified ribbons have been produced by a planar flow casting. Calorimetric and thermomechanical investigations as well as XRD, TEM/SAD and metallography observations have been performed. The martensitic transformation characteristics of the ribbons are studied and compared to those of bulk samples. The functional propel-ties have been measured for unidirectional deformation in cooling/heating cycles under a fixed load (the shape memory schema), and in tension at fixed temperature and subsequent heating/cooling stages (the superelastic, shape memory and I eversion stress schemes). Microstructure features and their influence on the martensitic transformation are analyzed with respect to the variation of functional properties.
