This is a very timely review of body armour materials and systems since new test standards
are currently being written, or reviewed, and new, innovative products released. Of greatest …

Amorphization of crystalline structures is a ubiquitous phenomenon in metals, ceramics, and
intermetallic compounds. Although the amorphous phase generally has a higher Gibbs free …

Dislocation slip, deformation twinning, phase transformations, and fast fracture are energy
dissipation mechanisms that accommodate mechanical loading in materials. The …

Ceramic armour materials are designated to protect personnel and vehicles against ballistic
damage. The main effort is now focused on developing ceramics with difficult-to-obtain …

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 is extremely hard but has been shown to undergo stress-induced
amorphization when subjected to large nonhydrostatic stresses. This localized …

Among hard materials, icosahedra-based boron-rich ceramics are only second to diamond-
based structures. This class of ceramics possesses lower density, higher thermal and …

This investigation deals with the study of 1 wt% carbon nanotube (CNT) reinforced high
velocity oxy-fuel sprayed conventional and nanostructured WC-Co coatings deposited on Ti …

Icosahedral boron-rich solids fall second in hardness to diamondlike structures and have
been the subject of intense investigations over the past two decades, as they possess low …

Homogenous distribution of whiskers in the ceramic matrix is difficult to be achieved. To
solve this problem, B 4 C-SiC w powder mixtures were freeze dried from a slurry dispersed …
