Literature Data

Over the last many years several researchers have investigated the Al-Cu-Ni system due to the interest in thermoelastic martensitic transformation exhibited by certain alloys of this system. This property is responsible for the unique mechanical behavior of these alloys such as shape memory effect, superplasticity and stress-induced martensitic transformations. These alloys have the potential to be used at higher application temperatures (≈200°C) than the conventional shape memory alloys found in Al-Cu-Zn and Ni-Ti systems (≈100°C) [1990Ye, 1998Pel, 2001Mot], even though it suffers from deterioration of mechanical properties due to grain boundary embrittlement [1984Hus, 2001Mot...
