CERT test

From the results one finds a relatively narrow scatter band of values in the da-dN diagrams for various frequencies (0.1-1 Hz) and R values (0.2-0.7). Furthermore, the stress corrosion cracking behaviour was determined using CERT tests here electrochemical potentials as well as fracture type and crack growth rates were determined. [Pg.15]

Carbon additions (here from 0.003 to 0.10%) in the steel lead to considerably higher stresses during the CERT test (evidently carbon strengthens the hardening effect through irradiation)... [Pg.43]

By means of CERT tests the influence of microstructure on the stress corrosion cracking behaviour of solution annealed (1100°C/20 min) Alloy 600 in deaerated (< 10 pg/1 oxygen) high purity water at 360-400 °C was examined [158]. Intergranular stress corrosion cracking is always found at these temperatures. Increased carbon contents in the matrix cause a reduction in the percentage of transgranular frac-... [Pg.59]

The influence of the potential on the susceptibility to stress corrosion cracking of sensitised (615 °C/10 h) filler materials made of Alloy 182 (67 Ni, 14.12 Cr, 7.44 Mn, 7.43 Fe, 0.41 Ti, 1.95 Nb) in high purity water with < 0.2 pS/cm, pH 6, at oxygen contents up to 200 mg/1 and 288 °C was examined [168]. Test methods included CERT tests and CBB (creviced bent beam) tests. The potential was adjusted using oxygen dosing, see Figure 27. [Pg.62]

Material research on SCC for SCWR has mainly focused on assessing susceptibility to SCC initiation using SSRT and CERT testing only a few fracture mechanics-based CGR tests have been conducted in SCW. Janik [125] constructed a phenomenological map of SCC indication with respect to dissolved oxygen content in SCW and applied strain rate for 316L using available data (Fig. 4.30). [Pg.137]
