| 抄録: | Post-irradiation annealing experiments were used to study the recovery of
microstructure and mechanical properties in V-Cr-Ti and V-Fe-Ti alloys
irradiated at 228°C to 4dpa. After 500°C post irradiation annealing, dislocation
channeling occurred at deformed area in tensile specimens and significant loss
of ductility resulted. For post irradiation annealing above 600°C, recovery of
damage structure and tensile properties occurred and irradiation hardening
completely disappeared in V-3Fe-4Ti-0.1Si. Clear dislocation channels can be
seen mainly in deformed areas of specimens showing significant loss of ductility,
however, a pile-up of dislocations in channels was observed at a grain boundary
where the channel did not penetrate into the adjacent grain. It is assumed that
3
defect clusters were absorbed by mobile dislocations and no debris or segments
of defect clusters were left in clear channels of bcc metals and alloys under
post-irradiation deformation. |
