Atom probe tomography characterizations of high nickel, low copper surveillance RPV welds irradiated to high fluences
TL;DR: The Ringhals Units 3 and 4 PWRs in Sweden are pressurized water reactors (PWRs) designed and supplied by Westinghouse Electric Company, with commercial operation in 1981 and 1983, respectively as discussed by the authors.

Overcoming the drawbacks of plastic strain estimation based on KAM.
Rickard Shen,Pål Efsing +1 more
TL;DR: Modifications to KAM were verified against a similar misorientation metric based on grain orientation spread, which does not show sensitivity to these factors, and showed the same results where the grain size was correctly compensated for.

Nano-cavities observed in a 316SS PWR flux thimble tube irradiated to 33 and 70 dpa
TL;DR: In this article, the radiation-induced microstructure of a cold-worked 316SS flux thimble tube from an operating pressurized water reactor (PWR) was examined under two irradiated conditions, 33 dpa at 290 degrees C and...

Spatial correlation between local misorientations and nanoindentation hardness in nickel-base alloy 690
TL;DR: Misorientation increases with plastic strain in metals, and this observation has been used as an empirical assessment of plastic strain this paper, which has been validated for a sample a a sample in the literature.
