Effects of microstructure and material properties on the mechanical behavior of hot-pressed boron carbide are presented. The microstructure and intrinsic microstructural inhomogeneities have been characterized using scanning electron microscopy characterization techniques (SEM/EDS/EBSD). In-situ...

The dynamic response of hot-pressed boron carbide was studied under uniaxial and confined loading conditions using a modified compression Kolsky bar setup at strain rates of 102 – 103 s–1. The progression of damage in the prismatic specimens was captured using a high-speed camera. This...

In this paper, the impact-induced fragmentation of a commercially available hot-pressed boron carbide is explored. Fragmentation has been noted previously by many authors to be important in the impact performance of advanced ceramics, and so this paper seeks to provide some of the first...

A comparative study on the microstructure, rate-dependent compressive behavior, and ballistic performance of commercially available pressureless sintered boron carbide-titanium diboride (material Z) and hot-pressed boron carbide (material S) was conducted. Under quasi-static compression at rates...

The quasi-static confined uniaxial compaction of granular alumina and boron carbide was studied, and the effect of triaxial stress on the materials as a function of increasing particle size was observed. The average particle sizes studied for granular alumina were 170 ± 63, 230 ± 55, 330 ± 67,...
