Abstract

Nano-sized dense Si3N4 ceramics have been produced by high-energy mechanical milling followed by spark plasma sintering. The superplastic deformation of these ceramics is studied in compression over a wide range of strain rates and temperatures. Different deformation behaviors have been reported compared with that reported before for silicon nitride ceramics with sub-micron-sized grains.
