Abstract:

The pioneering research by Wilkins and colleagues in the 1960s led many investigators to conclude that ceramic armor performance could be significantly enhanced with materials macrostructurally designed to grade from a pure ceramic to a stiff, more ductile material at the back surface. Several configurations of TiB2TiBTi functionally graded materials were fabricated using a spark plasma sintering process. Detailed microstructural characterization of the as-processed material is presented as well as x-ray flash radiographs of penetrating projectiles in a reverse ballistic configuration using a 1-MeV x-ray system in a 100-mm gas gun apparatus. This report is a collection of the charts used for an oral presentation at the 28th International Cocoa Beach Conference and Exposition on Advanced Ceramics and Composites.
