Structure and thus properties of melt-spun CuAlNi-based alloys are mainly affected by the wheel speed and applied additional heat treatment. Increase in the wheel speed causes increase of the quenched-in vacancy concentration, grain refinement, rise of the columnar morphology and their privitaged orientation. The texture, which becomes sharper with the wheel speed increase, consists of a fibre [100] orientation and two sheet component orientations (100)<001> and (100)<011> related to the DO3-parent phase. The latter component increases after annealing the ribbons atm 900 <$E symbol Р >C. The reversible elongation during transformation under constant atress increases with the texture development. It also increases with increasing the load under which the shape recovery was measured. The annealed ribbons exhibit the induced two-way shape memory effect just after the first sysle under load. Effect of all these factors on shape memory and mechanical properties will be considered in the presented paper.
