Mixed Phase Effects in Aluminum
Final rept. 15 Apr 1970-31 Oct 1972

Pagination or Media Count:
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 calgm. Manganin gauges and the laser interferometer were used to obtain stress time records adjacent to the region of energy deposition.
