Fig. 3: SANS experimental set up and one-dimensional scattering intensities.
Experimental configuration used in the current SANS measurements. a One-dimensional nuclear scattering intensities versus scattering vector obtained from the Eurofer97, the present Stage 3 RAFM steel, and pure iron (as a reference). Error bars show the standard error. (See Methods, section “Small angle neutron scattering”, for the Porod Law which was discovered by Günther Porod, and describes the asymptote of the scattering intensity I(q) for large scattering wavenumbers q; q defined in Eq. (8)). The arrows show the direction the curve goes in for a reduction in Cr23C6 precipitates and nanoprecipitates such as MX. b An incident neutron beam transmitted through a bulk specimen containing nano-sized precipitates embedded in a ferritic matrix. c The resultant SANS two-dimensional pattern in the presence of a horizontal magnetic field. 2θ is the scattering angle, q is the scattering vector.
