Description
The objective of this effort is to improve understanding of the effect of fast neutron irradiation on microstructural evolution by examining the response of neutron irradiated pressurized tubes of a duplex ferritic/martensitic steel. 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 two pressurized tube specimens of JFMS, a duplex ferritic steel following irradiation in FFTF/MOTA at 407 C to 7.5 x 1022 n/cm2 (E > 0.1 MeV) or 37.5 dpa. Preliminary analysis of one set of micrographs indicates large anisotropy in Burgers vector populations for an 86 MPa stressed condition
