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 …

Due to its favorable physical, mechanical and chemical properties, boron carbide (B 4 C) is
one of the most important ceramics used in various industries. After diamond and boron …

The B 4 C matrix composite intended for armor applications still presents restrictions, such
as low sintering density, production of large parts and inherited brittleness. Herein, research …

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 …

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

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 …

Square-shaped boron carbide ceramic composites have been produced by spark plasma
sintering with the addition of 5 to 20 vol% titanium metal powder in the B4C matrix in order to …

Bilayered B 4 C-based ceramics were obtained by hot-pressing. Microstructure, mechanical
and ballistic properties of the bilayered ceramics were investigated. One layer was obtained …

This work discusses the pressureless sintering of a boron carbide-titanium diboride (B 4 C–
TiB 2) nanocomposite via in-situ reaction of the boron carbide/titanium dioxide/carbon …

In this study, boron carbide-metallic boride (B 4 C-MeB x, Me= Ti, Zr, Nb, Ta, or W)
multiphase ceramics were fabricated via in situ pressureless sintering at 2250° C for 1 h …
