Key Points

  • The aim is to investigate the effects of temperature on shear modulus and internal friction in multilayer metal composites.
  • Studied temperature dependence from 130 to 600 K.
  • Analyzed Cu–Ni, Ti–Ti5Si3, and EP678–Me3Al metal laminate samples.
  • Observed internal friction and shear modulus changes at different temperatures.
  • A peak in internal friction was noted below room temperature.
  • A stepwise change in shear modulus occurred in the initial state of the samples.
  • High-temperature annealing eliminated the observed features.

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.
