Ballistic tests are performed by shooting both tungsten fiber/bulk metallic glass W/Zr58Ti13Cu17Ni12 composite rods (composite rod) and tungsten heavy alloy rods (95W rod) into 30CrMnMo target. The composite rod exhibits self-sharpening behaviors, and its matrix damages and fibers break are limited in a thin, narrow area, which is defined as edge layer. Penetrating depth of composite rods is 50% deeper than the depth of 95W rods with same dimension size. (C) 2012 Elsevier Ltd. All rights reserved.
