WebEven with the appearance of metallic Fe for the particles on graphite, no Fe diffraction peaks are observed, indicating those Fe particles are not crystalline. Therefore, the presence of hydrogen during the annealing process affects both the particles’ morphology and crystallinity. WebThe annealing behavior of neutron-irradiated nuclear graphite was investigated using a precision dilatometer (DIL 402C, NETZSCH, Germany). Length changes of graphite specimens were continuously measured in situ from room temperature (~293 K) up to 1673 K with a step-heating temperature interval of 50 K in helium atmosphere.
