Effect of local strain and GND density on crack initiation in alloy 600
In this work, strain and geometric necessary dislocation (GNDs) have been measured around various grain boundaries after subjected to a 4-point bend test in simulated PWR primary water conditions, with the aim of clarifying which local conditions trigger SCC initiation. Three different regions are c...

| description | In this work, strain and geometric necessary dislocation (GNDs) have been measured around various grain boundaries after subjected to a 4-point bend test in simulated PWR primary water conditions, with the aim of clarifying which local conditions trigger SCC initiation. Three different regions are compared: in a cracked grain boundary, the cracked and the uncracked portions are compared to a similar grain boundary in the as-received material. l. To study this, “on-axis” Transmission Kikuchi Diffraction (TKD) with a step size of 1 nm followed by GND analysis and cross-correlation based strain mapping, was performed. Results together with a discussion on the limitations of the approach will be presented. |
