Metallurgical Examination of Fourteen 3/8 in Rolled Homogeneous Armor Plates

Abstract

Metallurgical examination, including Brinell hardness determinations, macroetch tests, fracture tests for steel soundness and response to heat treatment, and microscopic examination, was conducted on each of fourteen (14) 3/8 in. homogeneous armor plates furnished by Great Lakes Steel Corporation and tested at The Ordnance Research Center as a part of the effect of hardness program. Steel soundness, with respect to freedom from laminations, was satisfactory in all plates except one. All plates had been satisfactory heat treated as indicated by the fibre test and microscopic examination.
