Abstract:

Five out of six of the 12-in. samples showed an extremely laminated condition in approximately the same location in each section. In other areas of the section, virtual absence of lamination was apparent. This poor condition occurred approximately in the center of the section as received and would seem to indicate a constant malpractice either as regards ingot design or as regards cropping procedure. The ballistic test plates may be expected to show variable results in different areas of impact.
