Abstract
Fracture regions in a nickel alloy have been investigated by electron microscopy. HfO2 particles are mainly found in the fatigue crack zone. Their morphology and crystal structure are determined. The formation (with a relatively low concentration) of such particles and precipitates, containing Са, S, and other elements, is most likely related to the organic contamination of material.
