Spatial Distribution of Amorphization Intensity in B4C during Rate-Dependent Indentation and Ballistic Impact Processes [1.2 Solid Mechanics]

Abstract

At high pressures, such as those encountered in ballistic impact, boron carbide (B4C) suffers from loss of crystallinity, referred to as a morphization, to form nanometer scale amorphous bands. Through experimental and theoretical investigations, current research seeks to enhance our understanding of B4C crystal structure(polymorphism) so as to explore novel avenues for improving its resistance to a morphization.
