Abstract:

The effect of second phase particles in different shapes on grain growth of AZ31 Mg alloy has been simulated by the phase field methods under realistic spatial-temporal scales. The long-range orientation field variables are chosen to express the temporal microstructure evolution and crystal orientation. The expression of the local free energy density equation was modified by adding the expression term of second phase particles, and the simulated results show that the grain boundary migration is pinned by the second phase particles during the grain growth, which is agree with the Zener pinning observation. When the shape of particles is different and the volume fraction is 10%, the effect of refining grain is different too, the oval particles are the strongest, followed by the rod particles, and the effect of spherical particles are weaker. The research will help to understand the mechanisms of grain growth containing the second phase particles strengthening.
