Effect of Plate Temperature Upon the Performance of Homogeneous Armor

Abstract

Variations of the hardness and ballistic resistance of homogeneous steel armor with temperature were determined for several different compositions and hardnesses at Cal. 30 and Cal. 50 scale. Sufficiently ductile material exhibits an increase in hardness and ballistic resistance on cooling and a decrease on heating. The increase in hardness by cooling results in greater ballistic resistance than the same increase in hardness obtained by heat treatment. However, it is shown that harder material may exhibit brittle failure and decreased ballistic resistance when cooled.
