Metallurgical Examination of 4 in. Thick Cast Armor.

Abstract

Metallurgical examination was conducted on a 4 in. thick cast plate No. C977B-1, heat 2934 submitted by American Steel Foundries, East Chicago Plant. This plate failed to meet 155mm, shock and 90mm, ballistic limit requirements of specifications AXS 1013. The results of this investigation indicated that the material was incompletely quench hardened due to inadequate hardenability and that it showed some evidence of embrittlement by temper brittleness (not pronounced).
