Effect of mechanical activation on the sintering of transition nanoscaled alumina
Source abstract
Abstract
Consolidation of transition nanoscaled alumina (?, ?, ?, and ?-phase) at P=500 MPa and T=1500?C, gave compacts with density of 70%TD and a vermicular structure. After mechanical activation by attriting, the transformation rate of ?-Al2O3? ?-Al2O3 ? ?-Al2O3 ? ?-Al2O3 was reduced from 1126 to 1079oC. The density of the sintered compacts at 1500oC was 96%TD. The ?-Al2O3 microstructure exhibited a grain size distribution from 100 to 900 nm.
