“…22) According to previous reports, [23][24][25] NaCl-type VCx with a varying fraction of carbon (x value) is the first candidate for the precipitate in V steels in this temperature and size range. Figure 8 shows the values of Δρx 2 /Δρn 2 calculated from the chemical composition and crystal structures using literature data.…”

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.

“…The V-C system has been experimentally investigated many times over the years [4][5][6]. A critical review of the available information on the phase equilibrium, crystallography and thermodynamic properties of the system covering 0-60 at.% C was presented by Carlson et al [4], and the assessed phase diagram was accepted in the compilation of binary alloy phase diagrams [5].…”
