The ageing process in the CuAlNi+TiB alloy may be performed as a three stage process. The first stage causes a decrease in characteristic temperatures of transformation, in hardness and electrical resistivity. It is probably due to annealing out of vacancies of the alloy as well as to ordering process. The second and third stages were identified as connected with the coherent and noncoherent precipitation of γ2 particles. The change of shape recovery temperature in the second stage was expressed as a function of time and temperature of ageing.
