THE EFFECTS OF EXPLOSIVELY INDUCED STRESS WAVES ON THE MECHANICAL PROPERTIES OF SEVEN METALS,

Abstract

An oblique stress wave of approximately 160-205 kilobars was induced in metal specimens of cupro-nickel, inconel, monel, 'A' nickel, stainless steel, and low carbon steel by detonation of TNT, H-6, and Composition B explosives in direct contact. The effects of this stress application were to increase tensile strengths by 18 to 107%, to increase hardnesses 49 to almost 200%, and to reduce impact strengths approximately 30 to 80%, depending on the type of metal and explosive. Composition B explosive was found to produce a greater change in the mechanical properties than either TNT or H-6. (Author)
