The trajectory follows a straightforward dependence on density as illustrated using data for a wide variety of materials and consolidation conditions.
Most materials sinter by a combination of densification and nondensification mechanisms.
Comparison of surface area loss during sintering using the sintered density as means to differentiate the trajectories for different materials.
