Abstract Based on a new three-dimensional topology-related grain growth rate equation proposed recently by MacPherson and Srolovitz, a set of analytical quasi-stationary grain size distributions were obtained. One of such distribution functions can be used to describe satisfactorily the three-dimensional quasi-stationary grain size distribution obtained from experimental measurement results for pure iron by serial sectioning, and those obtained from computer simulations by vertex method, surface evolver method, phase-field method, Monte Carlo method with Potts model. The corresponding grain size distribution curve is very similar with those of available theoretical quasi-stationary grain size distributions in literature.
