Abstract
Dynamic modulus and internal friction measurements have been carried out on Al samples directly during creep deformation. The measurements have been accompanied by observations in transmission electron microscopy. Creep curves, dynamic modulus and TEM data have been utilized for analyses with the φ(l) functions giving the distribution of dislocation segments both mobile and non-mobile.
