“…Measurements were taken at nine equidistant points, calculating the resulting average value of the crack by the following equation. 19 a, -fan a = [2] The numerical results obtained in the tests, together with their duration, are summarised in Table 4. A graph of crack growth rate versus stress intensity factor K average , taken as the average between K initial at the beginning of the test and K finaI , is shown in Fig.…”

Dissimilar welds, used to join different sections in light water reactors, are potentially susceptible to stress corrosion cracking (SCC) in aqueous media, characteristic of nuclear plants. However, the study of these welds has been limited to evaluating weld material susceptibility in these media. Scarce data are available on crack growth rates due fundamentally to inadequate testing techniques. In order to address this lack of information, the crack growth rate at the interface of ferritic SA533B-1 alloy and 1-82 alloy in a dissimilar weld (SA533B-1/I-82/316L) was studied. Experiments were conducted in water at 288 °C, 8 ppm of O 2 and 1 µS/cm conductivity.
