HIGH-ENERGY RATE-FORMING.
Abstract
Thin-wall 1015 and 4130 tubular steel specimens were bulged to a simple shape using explosive, electrohydraulic and cartridge-hydraulic techniques to determine the effects of structure and energy media upon the formability of the two materials. Maximum expansion (40 per cent) without splitting was obtained with the cartridge-hydraulic system on the spheroidized 4130 steel tube specimens. Pressures, rise times, strain rates, and metal-deformation velocities were determined for the specimens bulged with thecartridge-hydraulic system. Reduction of wall thickness and increases in hardness of the two materials in the bulged area were comparable for all three forming techniques in both the spheroidized and annealed conditions.
