Abstract
In this work we have studied the mobility of martensitic interphases on Cu-Al-Ni policrystalline shape memory alloys with different concentrations. For that reason we have used a microdeformation technic very useful for the study of the policrystalline alloys. This microdeformation measurement has let us to observe two transformation stages linked to [MATH] and [MATH] phases nucleation. Finally we discuss the effect of the internal stresses, stored during the quenching treatment, on the nucleation of the different martensitic phases.
