High-temperature deformation of Al2O3/Y-TZP particulate laminates Original Research Article

Al2O3/Y-TZP particulate laminates with varying compositions and ratios of layer thickness were fabricated by tapecasting, lamination, and sintering. The resulting particulate laminates were tested in compression at a temperature of 1350 °C over strain rates from 1.00 × 10−5 to 3.16 × 10−4 s−1. Microstructural changes during testing were observed to be minor. Stress exponents were measured to be approximately two and are consistent with previous data for particulate composites. Using parameters determined from particulate composites, the behaviors of the particulate laminate composites are accurately predicted using a constrained isostrain model without additional fitting parameters.
