Abstract

Liquid phase sintered materials are characterized by a connected microstructure composed of contacting grains in a solidified matrix phase. Observations on the sintered microstructure are typically performed using two-dimensional cross sections. A computer calculation has been performed to determine the variation in the observed contacts per grain vs the true underlying microstructure connectivity. The results show that the observed coordination depends on both the volume fraction of solid phase and the dihedral angle. The findings of the calculation are favorably compared with observations on Fe-Cu and W-Ni-Fe alloys. In the limiting case, the current calculations approach those found for polycrystalline solids and cell networks.
