Abstract

Temperature dependences of shear modulus and internal friction are studied in the range from 130 to 600 K for Cu–Ni, Ti–Ti5Si3, and EP678–Me3Al metal laminate samples. In the initial state of samples, at temperatures below room temperature, a peak in internal friction and a stepwise change in the shear modulus are observed. After high-temperature annealing, these features disappear. Possible mechanisms for this observed behavior are discussed.
