Structural ceramics are becoming widely popular in numerous fields because of high
mechanical and physical properties. It is of great difficulty for conventional techniques to …

Boron carbide (B 4 C) with good properties such as superior hardness, low density, high
melting point, high modulus of elasticity and chemical neutrality is considered an …

Spark plasma sintering (SPS) was employed to consolidate powder specimens consisting of
B 4 C and various B 4 C-TiB 2 compositions. SPS allowed for consolidation of pure B 4 C, B …

Non-destructive ultrasound phase spectroscopy (UPS) was used to study the influence of
thermal shock on the longitudinal elastic constant (C 11) of ZrB 2-B 4 C composites. C 11 of …

Boron carbide (B 4 C) is a ceramic with great properties such as low density, the third
hardness after diamond and cubic BN. However, it is a limited use cause of its poor …

To achieve lightweight B4C-based composite ceramics with high electrical conductivities
and hardness, B< sub> 4 C-TiB< sub> 2 ceramics were fabricated by reactive spark plasma …

Abstract TiB 2–20vol% B 4 C (TB20) and TiB 2–80vol% B 4 C (TB80) ceramic cutting tool
materials were prepared by hot pressing, and then tested in turning of Ti6Al4V alloy with …

Boron carbide ceramics have broad application prospects due to their excellent
performance. However, their poor sinterability and low fracture toughness limit their …

Abstract Ternary B 4 C-SiC-ZrB 2 ceramics with eutectic compositions were prepared in situ
by reactive spark plasma sintering at 1600–1800° C. The two-step sintering, including an in …

Abstract B 4 C-TiB 2-SiC composites were fabricated via hot pressing using ball milled B 4
C, TiB 2, and SiC powder mixtures as the starting materials. The impact of ball milling on the …
