Abstract
A densified ceramic or cermet armor material comprises greater than fifty percent by weight titanium nitride or greater than eight percent by weight of a mixture of titanium nitride and aluminum nitride to impart low compressive strength to said armor material and may additionally comprise components suitable for densification with said titanium nitride or titanium nitride-aluminum nitride mixture where the resulting armor material has high density and low porosity with a Young's modulus greater than 200 GPa and a compressive strength of less than 5.5 GPa.
