Abstract:

An experimental cast tank turret, for a medium tank was subjected to ballistic tests which indicated that the area adjacent to the base ring offered considerably less resistance to penetration than the side of the turret away from the base ring under the impact of 75 mm. M61 armor piercing projectiles at an obliquity of 48 deg from normal. No difference were observed in the metallurgical properties between the two areas in question, to which the variation in ballistic properties could be attributed. The steel was relatively sound and free from casting defect in the sample examined. The casting would be considered rejectable, however, because of improper heat treatment.
