Phase Field Simulation of Precipitation on Edge Dislocation

Article Preview

Abstract:

The second phase nucleation and precipitation around an edge dislocation are studied using phase field method. A new free energy function including the elastic strain energy is established to describe the dislocation interaction with the solute. The results give the distribution of strain field of dislocation and show the precipitates grow up according to the power growth law with the index 2. The simulated results are in good agreement with that of theory of non-uniform nucleation.
