Ductility and creep resistance of a silicon nitride ceramic

Careful choice of the sintering conditions of alpha-Si3N4 powder can yield a high ductility microstructure exhibiting high ductility and therefore suitable for the hot-forming of complex structural components to net shapes. Subsequent heat treatment can be used to develop a microstructure with high...

Summary:Careful choice of the sintering conditions of alpha-Si3N4 powder can yield a high ductility microstructure exhibiting high ductility and therefore suitable for the hot-forming of complex structural components to net shapes. Subsequent heat treatment can be used to develop a microstructure with high mechanical properties. (AIAA)
