Averaged Voronoi Polyhedron in the Equiaxed Solidification Modelling

Mostrar todas las versiones(2)

For the modelling of the equiaxed grain growth controlled by diffusion the spherical Elementary Micro-Diffusion Field (EMDF) is usually used. Unfortunately, deviation of the idealized spherical grain geometry from the real one increases with a distance from nuclei. The proposed model of the equiaxed...
