Abstract:

The object of this study was to correlate the subzero temperature ballistic properties of the vast tank turret with the metallurgical characteristics of the steel. The report concludes that ballistic failure is not attributable to the poor steel quality. Reheat treatment is capable of producing physical properties believed adequate to withstand low temperature ballistic shock tests.
