Fig. 3: Defocus transmission electron microscopy images from the irradiated region of ODS-NiCoFeCr.
From: Nanostructured NiCoFeCr alloy with superior high-temperature irradiation resistance
Infocus, underfocus, and overfocus images illustrate the no occurrence of irradiation-induced voids in various grains at the depths of a–c 0.27 µm, d–f 0.5 µm, g–i 0.72 µm, j–l 1 µm, and m–o 1.5 µm from the surface. The black arrows indicate the location of the grains under examination and the blue arrows represent the oxide nanoprecipitates with loop-like contrast.
