Processing of Tape–Cast Laminates Prepared from Fine Alumina/Zirconia Powders

This paper addresses the effect of thermocompression pressure, shear deformation of green laminates, and postsinter HIPing on the microstructural homogeneity of cast tapes and laminates prepared from fine Al 2 O 3 , and Al 2 O 3 / ZrO 2 , powders. Green density increases with increasing thermo–compression pressure. Sintered densities, however, depend more on the macroscopic uniformity in the green tapes. When density gradients develop within …
