The formation mechanism of nanoscale core-shell precipitates within multicomponent alloys has been revealed to involve a combination of thermodynamic and kinetic processes. Ab initio calculations were used to determine the interactions between the constituent atoms, and these interactions were used as inputs in a Monte Carlo model for atomic motion. A unique aspect of this work is that it these simulations were tested using a wide array of experimental techniques. The results showed a new nucleation and growth mechanism of the precipitates, while Zr laying an important role in both processes. The kinetics of the diffusion process obviously plays an important role in the development of the core-shell nanoparticles.
