Metallurgical Examination of Six 1/2 Inch Rolled Homogeneous Armor Plates Manufactured by Great Lakes Steel Corporation

Abstract

Metallurgical examination including Brinell hardness surveys, fracture tests for steel soundness and fibre, and macroetch tests, was conducted on each of the six plates furnished by Great Lakes Steel Corporation. Microscopic examination was made on two plates and a chemical analysis taken of one. All plates were satisfactory with respect to steel soundness. The plates at hardnesses of 388 Brinell and above developed some crystallinity in the fibre fracture test. Crystallinity in this material is attributed to tenner embrittlement.
