摘要：

The mechanism of the so-called rubberlike elasticity in shape memory alloys such as Au-Cd and Cu-Au-Zn alloys is investigated using the measurement of static and dynamic elastic moduli. A large difference between the static and dynamic elastic moduli is found. While the dynamic modulus remains almost unchanged during room-temperature annealing for 3 days. the static modulus increases appreciably during the same annealing, corresponding to the appearance of the rubberlike elasticity. These experimental results are discussed in terms of the pseudoelasticity due to twin boundary motion.
