20.500.12556/DiRROS-16843 Stress corrosion crack initiation testing with tapered specimens in high-temperature water - results of a collaborative research project The applicability of an accelerated test technique using tapered tensile specimens for investigating the stress corrosion crack (SCC) initiation behaviour of structural materials in high-temperature water was assessed in the framework of a European collaborative research project (MICRIN – MItigation of CRack INitiation). The main advantage of using a tapered geometry is, that in a single test a stress gradient is obtained through the gauge length, and therefore a stress threshold for SCC initiation can be determined in a reasonable timeframe. This method was used to investigate two different materials that were known to be susceptible to SCC in light water reactor environment: a high-Si stainless steel and a Ni-base weld metal (Alloy 182). The results of the international test programme confirmed that the tapered specimen test methodology could be used to identify a SCC initiation stress threshold, albeit that significant scatter was present in the data. stress corrosion cracking surface finish impact tapered tensile specimen autoclave accelerated testing light water nuclear reactor critical threshold stress napetostno korozijsko pokanje vpliv površinske obdelave trapezast natezni vzorec avtoklav pospešeni test lahkovodni jedrski reaktor mejna napetost true false false Maney for the Institute of Materials, Minerals, and Mining Angleški jezik Slovenski jezik © 2020 The Author(s).
