Abstract
The independence of temperature shown by the strain hardening coefficient of face centred cubic metals appears to be at variance with several other features of this strain hardening that depend on temperature. However, on the forest theory of this hardening, thermal activation is expected to have opposite effects on two underlying aspects. First, it reduces the applied stress required to enable glide dislocations to cut through forest obstacles. Second, it increases the density of the secondary dislocations that form these obstacles so that the forest becomes harder to penetrate.Keywords
