Growth kinetics of omega particles in beta-Ti matrix studied by in situ small-angle X-ray scattering
Original language description
Nucleation and growth kinetics of nanoparticles of hexagonal omega phase in a body-centered cubic beta titanium matrix in single crystals of beta-Ti alloys were investigated by small-angle X-ray scattering measured in situ during ageing at various temperatures up to 450 degrees C. The experimental data were compared with numerical simulations based on a three-dimensional short-range order model of nanoparticle self-ordering. The X-ray contrast of the particles is caused by an inhomogeneous distributionof impurity atoms (Mo, Fe and Al), whose density profile around growing nanoparticles was simulated by solving the corresponding diffusion equation with moving boundary conditions. From the analysis of the experimental data we determined the mean distance and size of the nanoparticles and confirmed the validity of the alpha t(1/3) OP growth law following from the Lifshitz-Slyozov-Wagner theory. From a detailed comparison of the experimental data with simulations we also assessed the diff
