Asle Zaeem, M., El Kadiri, H., Wang, P., & Horstemeyer, M. (2011). A Phase-Field Model for Recrystallization Grain Growth: Effects of Grain Boundary Energy Anisotropy and Second-Phase Particles. TMS 2011 Annual Meeting & Exhibition.

We use a phase-field model to investigate the effects of grain boundary (GB) energy anisotropy and the presence of second-phase inert particles on grain growth (GG) in polycrystalline materials. Different conditions are studied. System of grains with anisotropic GB energies is considered by including models of low and high misorientation angles between adjacent grains. Systems without particles reach a steady state grain growth rate and this rate decreases by including GB anisotropy. The presence of particles significantly alters the microstructures during grain growth. It was shown that for systems with particles the critical average grain size to stop grain growth depends not only on volume fraction and size of particles but also on GB anisotropy.
