Abstract:The influence of prestrain and static strain aging on the cleavage fracture stress ?f in a C–Mn steel has been investigated. It is shown that ?f increases with increasing amount of prestrain and that the effect of strain aging is to reduce slightly the value of ?f. Smith's original theory for cleavage fracture in steel containing grain-boundary carbides is used to determine the effect of prestrain and strain aging on the effective surface energy ?eff of crack propagation. It is shown that ?eff is approximately prestrain independent and that strain aging makes ?eff decrease slightly.
