Fig. 4: Scanning transmission electron microscopy—Bright field images from the irradiated and pristine regions of ODS-NiCoFeCr.
From: Nanostructured NiCoFeCr alloy with superior high-temperature irradiation resistance
The two-beam conditions images captured with g{220} illustrate the presence of irradiation-induced dislocation microstructures in various grains at a depth of a 0.3 µm, b 0.4 µm, c 0.5 µm, d 0.7 µm, e 0.9 µm, f 1.0 µm, g 1.5 µm, and h 3.5 µm from the surface. The blue, green, and yellow arrows represent the dislocations, oxide nanoprecipitates, and the pinning of dislocations at the oxide nanoprecipitates, respectively.
