Title: Role of residual stresses in stress corrosion cracking in alloy 600 tubes. Part 1. Determination of throughwall residual stresses and their modification by transient heat treatment

Abstract

The effect of transient heat treatment on throughwall residual stress distribution of cold worked Alloy 600 tubes has been investigated, using electrochemical machining coupled with Sachs analyses for residual stress calculations. Heating for 60 to 150 seconds at 775 to 850 C is used. Specimens are made from one highly cold worked and one lightly cold worked tube. In both cases significant reduction of the magnitude of the stress, and modification of the stress distribution are achieved as a result of the heat treatment. The percentage reduction of the magnitude of the stress caused by the same heat treatment is generally greater in the lightly cold worked tube than in the highly cold worked one. The implications of the stress relieving heat treatments to mitigating stress corrosion cracking in a specific case are discussed. 14 references, 17 figures, 1 table.
