N2 - The dynamic response of a titanium carbide (TiC)‐carbon steel, ceramic‐metal composite, was studied in planar impact experiments, using a copper impactor with velocity in the 80 to 450 m/sec range. The composites were prepared by pressureless infiltration of TiC ceramic preforms with molten steel. The metallic component had either a pearlitic or a martensitic microstructure, determined by an appropriate heat treatment. Fully dense composites, consisting of TiC and 1060 steel, in pearlitic and martensitic states, were used as reference samples. The values of the HEL and of the spall strength were derived from the VISAR records of the free surface velocity of the impacted samples. The results indicate that the confining stress, produced by metallic matrix on the TiC particles, changes drastically the dynamic response of the composite.
