The deformation properties of a new group of the Cu-Al-Nb (up to about 8 wt.% Nb) base alloys exhibiting the shape memory effect at elevated temperature were the subject of this work. Niobium, which solubility in copper is low, exists in these alloys in a form of primary precipitates of intermetallic phases, mainly the Nb(Cu,Al)2 Laves phase. The carried out studies have shown that the primary precipitates of the intermetallic phases on the niobium base play a basic role in a simultaneous strengthening and increase in plasticity of these alloys.
