Microstructure Evolution Behavior of Metastable SiBCN Ceramics Prepared by Mechanical Alloying

The fully dense amorphous Si-B-C-N monoliths were fabricated at 1000°-1600°C under5 GPa for 30 min where the mechanically alloyed amorphous Si-B-C-N powders were used as raw material.Crystallization and microstructure evolution of the prepared ceramics were

The fully dense amorphous Si-B-C-N monoliths were fabricated at 1000℃-1600℃ under 5 GPa for 30 min where the mechanically alloyed amorphous Si-B-C-N powders were used as raw material. Crystallization and microstructure evolution of the prepared ceramics were investigated by XRD, TEM and HRTEM.
