In this work, TaC ceramics with a high density (98.6%) and fine grains (1.42 µm) were
fabricated by high pressure sintering. The as-sintered specimen possessed a high …

The B 4 C-diamond composite with high hardness and toughness was first prepared by high-
pressure sintering of B 4 C and diamond powders at 5 GPa and 1600° C. The effect of the …

Previous research have reported that B 4 C–TiB 2 composites could be prepared by the
reactive sintering of TiC–B powder mixtures. However, due to spontaneous oxidation of raw …

In this research, B 4 C-TiB 2 composites were successfully fabricated via the spark plasma
sintering method. First, the TiB 2 source effect on the B 4 C-TiB 2 composites was …

The preparation of dense Si3N4-based ceramics has attracted great attention due to the
achievable improvements in mechanical properties and high-temperature oxidation …

Harsh synthesized pressure is required in constructing of excellent grain boundary (GB)
connection for nano-polycrystalline cubic boron nitride (nPcBN) to yield high hardness and …

Boron carbide ceramics (B4C) have extraordinary hardness and well‐abrasive resistance,
while the tribological behavior of ceramic materials is complicated, which are affected by …

Nanotwinned diamond (Nt-D) possesses extremely high hardness and excellent fracture
