Grain Growth in Materials with Mobile Second-Phase Particles
Grain growth controlled by particles able to move together with grain boundaries is investigated by means of numerical simulation. The particles either located on grain boundaries or randomly distributed over the material volume are shown to retard the growth process. In the first case the growth kinetics is described by a power law Dn −D0 n = kt with the exponent n≤ 3. Growth kinetics under the influence of randomly distributed mobile particles can be approximated by the same law with the exponent n increasing with an increase in the particle volume fraction.
