The effect of post-quench heat treatments on the transformation characteristics and on the physical properties of a fine grained Cu-Al-Ni-Mn-Ti high temperature shape memory alloy are investigated by means of differential scanning calorimetry (DSC), X-ray powder diffraction, thermoelectric power (TEP) and hardness measurements. The changes during a posterior ageing in the martensite state, just below the As temperature, are described by three stages, and explained in terms of order and precipitation processes.
