Abstract
A single relationship was found between the magnitude (at a standard temperature) and the temperature-dependence of the flow stress after deformation at 173, 293 and 373°K. After equal strains at different temperatures the flow stresses were also simply related. These observations suggest that the ‘mechanical equation of state' fails because deformation at higher temperatures produces fewer obstacles to glide, rather than because of a temperature-dependent softening process (dynamic recovery).Keywords
