Sintering of high melting point nanopowders. II. non-isothermal sintering of nanopowders of titanium nitride

摘要

New technological approaches to sintering of nanocrystalline high melting point powders have been studied at present work Using rate-controlled sintering of TiN nanopowders we have obtained dense nanocrystalline ceramics with grain size 50 nm and nanohardness 28,8±2,47 GPa. Investigation of TiN grain structure evolution during sintering process allowed us to pass optimization of process and decrease temperature down to 1150 ℃.
