摘要：

Measurements during deformation show that in stationary creep the Kê peak diminishes, whereas the dynamic modulus relaxation remains nearly unchanged. From the correlations between internal friction and creep, apparent activation volumes are evaluated. Results are discussed in terms of diffusive motion of lattice dislocations contributing to the Kê peak. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
