Abstract
This study proves that initial density gradients have lasting detrimental effects on final dimensional tolerances. X‐ray computed tomography has been used to quantify changes in density following sintering; associated dimensional changes have been monitored using a laser micrometer. Nonuniformities present in the green state are still present at an overall relative density of ∼73%; in fact, these nonuniformities are exaggerated. Major losses of dimensional tolerance are triggered by the initial density gradients.
