Shear Modulus and Internal Friction in Multilayer Metal Composites

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.

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.
