The Snoek peak and the strain amplitude dependence of internal friction were measured in order to gain further information on the behavior of interstitial solute atoms in Fe-3.48%Ni alloy which had been neutron-irradiated and annealed. This alloy contained 37ppm N and 7ppm C.
Interstitial solute N and C atoms were trapped by irradiation-induced defects and released by annealing at above 250°C. The Snoek peak and the slope of Granato-Lücke plots which latter is proportional to 1/Lc (Lc being the dislocation loop length between impurity atoms) increased with annealing temperature.
The binding energy of interstitial solute N atoms to dislocations in the irradiated and annealed specimen was obtained from the strain-amplitude dependent internal friction. The value was about 16, 500cal/mol.
