Abstract : IENTIFIERS: Exploding Wires. Research is continuing on hypervelocity particle effects on materials: Two major advances were made: (1) Higher particle velocities were attained by using a specil fast-discharge capacitor; and (2) hypervelocity data were obtained using Cu and Al particles. In addition, new diagnostic experiments were conducted to study the exploding wire gun. Mylar partcles were accelerated to a velocity of 102,000 ft/sec. Good single-paricle impacts were obtained. Some ablation of the paticle (initil mass of 1 mg) occured. Extensive data of Al- and Cuparicle impacts on quasi-infinite Pb targets were taken. It is concluded that (for particle velocites above a certan level) the same crater shape is obtained for the disc-shaped partces that is obtined for spherical partcles (or projectiles) by other researcher.
