The use of CuZnAl industrial shape memory alloys requires to approach the questions of their stability and their transformation temperatures in the long run. We have investigated the influences that have education and time periodes between the several processing phases for several annealing times at 100°C. These three parameters have an effect not only on the alloy transformation temperatures but also on the evolution kinetic of these temperatures in the long run. This fact requires an exact characterization of the alloy state in order to master the industrial reproduction of such processings.
