Mixed Phase Effects in Aluminum

Abstract

A combined experimental and theoretical investigation of the radiation-induced impulse and stress generation characteristics of aluminum has been carried out for cases where a significant portion of the blowoff material was in the liquid-vapor state. Intense pulsed electron beams were used as a source of rapid (50 nsec) high-energy-density loading to produce mixed-phase effects in aluminum. Impulse measurements were obtained with a ballistic pendulum for peak doses of up to 3800 cal/gm. Manganin gauges and the laser interferometer were used to obtain stress time records adjacent to the region of energy deposition.
