Abstract

A study of fragmentation behavior in a Ni+Al structural energetic material was undertaken. Rings were fabricated from a Ni+Al structural energetic material and subjected to explosive fragmentation. Photon Doppler Velocimetry (PDV) data and ring fragments were collected and analyzed. Fragment sizes were found to be much smaller than those typical of ductile metals like copper and aluminum. This is attributed to the unique microstructure of the Ni+Al material. Additionally, a TNT charge cased with Ni+Al was detonated to cause the fragmentation of the Ni+Al case; high-speed photography showed Ni+Al fragments igniting upon oblique impact with a white photographic background.
