Phase Transformation and Densification of hBN-TiN Composites Fabrication by Spark Plasma Sintering

Article Preview

Abstract:

hBN-TiN Binary Composite Was Fabricated Using Spark Plasma Sintering (SPS) at Temperatures between 1973 and 2273 K. With Increasing TiN Content from 10 to 90 Vol%, the Relative Density Increased from 75.7 to 96.4%. The Maximum Relative Density of 96.4% Was Achieved in the hBN-TiN Containing 90 Vol%TiN Sintered at 2273 K. hBN and TiN Was Stably Coexisted at 1973 K without TiB2 Formation.
