Boron carbide is characterized by a unique combination of properties that make it a material
of choice for a wide range of engineering applications. Boron carbide is used in refractory …

Boron carbide is a strategic material, finding applications in nuclear industry, armour for
personnel and vehicle safety, rocket propellant, etc. Its high hardness makes it suitable for …

Room temperature fracture toughness and hardness of spark plasma sintered pure B 4 C
ceramics with grain sizes ranging from 120 nm to 17 μm have been studied. Vickers …

The densification behavior of boron carbide without sintering additives is reported for
temperatures in the range of 1100° C to 1800° C by spark plasma sintering (SPS) technique …

A new ceramic sintering approach employing plastic deformation as the dominant
mechanism is proposed, at low temperature close to the onset point of grain growth and …

Ceramics typically have very high hardness, but low toughness and plasticity. Besides
intrinsic brittleness associated with rigid covalent or ionic bonds, porosity and interface …

Toughening of super-hard B4C ceramics with ultra-fine grained microstructures via the
addition of SiC (15wt.%) or the simultaneous addition of SiC (15wt.%) and graphite (2wt.%) …

Spark plasma sintering (SPS) parameters are reported to have a remarkable effect on
microstructure and fracture toughness of boron carbide. Fully dense fine-grained boron …

In this paper we review the work related to amorphization under mechanical stress. Beyond
pressure, we highlight the role of deviatoric or shear stresses. We show that the most recent …

Boron carbide (B 4 C) is an important structural ceramic material, however, the use of this
material is limited by its poor sinterability and low fracture toughness. Nano-sized powders …
