Paper Title:
Influences of Annealing and Deformation on the High Temperature Internal Friction Spectra of Al-0.013%Wt Ce Alloy
  Abstract

By using a low frequency inverted torsion pendulum, the high temperature internal friction spectra of Al-0.013wt%Ce alloy subjected to deformation at different tensile rates was measured, and three peaks, the conventional grain boundary peak (P1), the bamboo peak (P2) and the soild solution peak (P3) were found. Increases of annealing temperature and deformation rate make P1 and P2 lower with P1 shifting to higher temperature and P2 to lower temperature. P3 was only found in the as-received samples. The dependence of P1 and P2 on grain size indicates that the two peaks are originated from the grain boundary sliding, and P3 may be associated with the diffusion of Ce atoms or other impurities at grain boundaries.
