摘要：

A procedure for determining the Burgers vector anisotropy in irradiated ferritic steels is described, allowing identification of all a < 100 > and all a/2 < 111 > dislocations in a region of interest. The necessary micrographs to apply the procedure have been taken of a pressurized tube specimen of JFMS, a duplex ferritic steel following irradiation in FFTF/MOTA at 407 degrees C to 7.5 x 10(22) n/cm(2) (E > 0.1 MeV) or 37.5 dpa, and a pressurized tube of JLF-1 irradiated at 430 degrees C under similar conditions to 14.3 x 10(22) n/cm(2) (E > 0.1 MeV) or 60 dpa. Analysis of micrographs indicates that large anisotropy in Burgers vector populations develop during irradiation creep.
