... is too large and the residual stresses cyclically relax to zero. As demonstrated in Fig. 4.3 , the loss would be most severe for an initially cold-worked material because of its high propensity for cyclic strain softening.

The cooling rate from annealing temperature must be controlled in such a way that residual stresses are not reinduced and that resolution effects are avoided. Typical practice is to cool from annealing temperature in the furnace or in still air...
