Abstract:

Correlations were established between ballistic shock properties and metallurgical properties, namely, V-notch Charpy impact values, fibre fracture test, and hardness. As a result of this investigation, it is indicated that 2 in. thick cast armor, heat treated to a fibrous condition at about 245-260 Brinell hardness may be subjected to a striking velocity of about 1200 feet per second, with a 105mm. proof projectile without causing undue cracking.
