INFLUENCE OF CRYSTALLOGRAPHIC AND METALLOGRAPHIC STRUCTURES ON DYNAMIC BEHAVIOR OF MATERIALS.
Abstract
An investigation was conducted to determine the ratio of dynamic to static yield strengths of four metal alloys having different crystallographic and metallographic structures. Thick-wall cylindrical tube specimens were hydrostatically loaded at low and high rates of strain to obtain circumferential yielding. The ratios on the inside and on the outside diameters of the specimens for the four materials investigated were as follows: stainless steel (FCC), 1.03 and 1.005; 4340 steel (BCC), 1.06 and 1.09; alpha titanium (HCP), 1.12 and 1.09; beta titanium (BCC), 1.26 and 1.29. Test procedure is given and results are discussed. (Author)
