Abstract
The influence of cold work on the susceptibility to stress corrosion crack initiation of a 3%NiCrMoV L.P. turbine disc steel has been investigated. Both corrosion pitting and stress corrosion cracking behaviour in a 5M sodium hydroxide solution have been measured on specimens prepared from material containing various amounts of cold work up to a maximum of 70% reduction in thickness. Observed variations in pitting and cracking behaviour are discussed in terms of the possible changes in the dislocation substructure introduced by cold working.
