“…(1) are also equal to those due to nuclear scattering and x-rays. Several research groups have previously reported the combined use of I mag (q) and I nuc (q) [33][34][35][36]. In this study, the ratio of I SAXS (q) to I  (q) is analyzed instead of I nuc (q).…”

The nanostructure of a Co-Pd-Si-O nanogranular film was investigated with the combined use of small-angle x-ray (SAXS) and neutron scattering (SANS). Using a new, compact type of SANS instrument, the SANS profiles of individual particles with a diameter of about 2-4 nm were successfully observed. The structures of magnetic regions were found to be the same as the chemical structures of the particles, and a sharp interface was observed between the matrix and the particles. The SAXS to SANS ratio clearly indicates that the particles are a CoPd alloy and the matrix is not pure SiO 2. In fact, the matrix is composed of a meaningful amount of Co.

“…In the following analysis we repeatedly refer to the concept of an 'average' cluster defined as a cluster composed according to the average composition of all irradiation-induced clusters in the probed volume of some 10 mm 3 . The effect of any internal structure of individual clusters (for instance core-shell structure [13]) is incorporated in the concept of an average cluster introduced above. This approach has been justified by reference to scattering theory [14].…”

“…2) Compared to TEM, the information obtained from the small-angle scattering (SAS) technique is quite limited, but it is a complementary and suitable technique to obtain average and representative values for the size of the precipi-© 2011 ISIJ tates. [8][9][10][11] However, few studies have used SAS on the microstructure of VC precipitates in steels. Recently, a new technique for quantitative analysis of the precipitates called alloy contrast variation (ACV) using small-angle X-ray (SAXS) and neutron scattering (SANS) was presented.…”

The microstructures and chemical composition of nano-precipitates in vanadium (V) steels were investigated by the alloy contrast variation method (ACV) using small-angle X-ray scattering (SAXS) coupled with small-angle neutron scattering (SANS) at holding temperatures ranging between 600 and 700°C. Both the SAXS and SANS profiles exhibited clear scattering, depending on the holding temperature, due to the presence of nano-precipitates. The scattering profiles of the precipitates are characteristic of spherical or disc-like particles. The average diameters of these precipitates increased from 0.5 nm at 600°C to 23 nm at 700°C, whereas the number density of the precipitates decreases with increased holding temperature. Therefore, the increasing holding temperature results in an increase in the growth rate of the precipitates. ACV analysis revealed that the chemical composition of the precipitates corresponds to NaCl-type vanadium carbide (VC) at 675 and 700°C, and as VC0.9 at 625 and 650°C. The formation of a different heterogeneity, non-NaCl type, was found in the sample at a holding temperature of 600°C. This probably corresponds to a precursor of the NaCl phase in the initial process of precipitation.
