Microstructure Development in a Porous Compact

Example densifieation by lattiee diffusion and grain growth by surface diffusion. 

To reduce G [oc (Z A)/ /Z)/Xs)], DJDi and Yi,Iys must be reduced. With the reduction of G, however, the region of pore/boundary separation is enlarged and pore/boundary separation can easily occur. An optimization is needed as always.
