Warm prestressing benefits in ferritic steels are mainly due to the creation of residual plastic zones in cases where initial and subsequent loadings are in the same direction. Current theories are based on this premise and are capable of predicting an apparent enhancement in cleavage toughness for stationary cracks and simple load-unload-reload cycles and associated temperature changes. The theories are strictly applicable only for conditions of small-scale yielding and two-dimensional geometries. The views of the UK Technical Advisory Group on Structural Integrity (TAGSI) on the current position are presented.
