Thermal ageing at constant temperature (350 C) and under systematically designed temperature varying conditions were performed on the metastable austenitic phase of hypoeutectoid Cu-Al-Be shape memory alloy Thermal precipitations and their effects on the alloy global microstructure were studied by DSC, XRD and SEM techniques Precipitations of equilibrium phases (alpha + gamma(2)) within the temperature range of 330-370 degrees C and their generalization by a discontinuous mechanism for an ageing time of 864 ks (240 h) were i
