Status Report on SPS TiB2/TiB/Ti Functionally Graded Materials (FGMs) for Armor

摘要

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 TiB2/TiB/Ti 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.
