A Study of Explosive Forming Selected Refractory Metals.
Abstract
Methods of investigating explosive forming of selected refractory metals to optimize the strain rate conditions are discussed. An approach involving the production of a DC voltage directly proportional to the forming velocity of metal blank was studied. The output voltage is measured and interpreted in terms of metal velocity, reaction time, and strain rate. A draw ring modification to the 4-in. cup die afforded better understanding of preform size and the achievement of deeper draws with less thinning and elongation than before. All draw ring work was completed with investigation of draw ring pressure. Elongation data of W plates was obtained after Cu plating the metal.
