Historical Review of the Correlation of Ballistic and Metallurgical Characteristics of Domestic Armor at Watertown Arsenal

Abstract

The correlation of metallurgical characteristics with ballistic properties has been a continuous, ever improving process. The correlation of microstructure, static and dynamic physical properties with the ballistic properties makes possible to utilize non-ballistic tests for inclusion into the specifications to eliminate unsuitable armor prior to ballistic testing. Later, for armor 6 in. and thicker, non-ballistic tests (hardness and V-notch Charpy) were substituted for ballistics. Today it is believed that the metallurgical characteristics required for optimum ballistic performance are known for homogeneous rolled and cast plate; the problem is one of achieving these characteristics, especially as the armor thickness increases. Furthermore, by means of hardness and fracture tests alone it is possible to predict ballistic results fairly successfully.
