FAST TRANSIENT HEATING AND EXPLOSION OF METALS UNDER STAGNANT LIQUIDS

Abstract
Thermnl transients with total pulse times of 3 to 28 milliseconds were simulated by direct-current electrical heating in studies of the explosions of Ag, Al, Cu, Sn, U, Zn, and Zr specimens under water and under oil at an ambient temperature of 75 d F and at atmospheric pressure. Motion pictures were taken of many of the explosions at film speeds of 7,500 to 14,500 frames/sec. A 600-foot composite reel was prepared which shows 7 representative explosions and views of the equipment. Data for 34 runs, photographs, and photomicrographs are presented and discussed with respect to burnout, heat transfer, and metal-- water reaction. (auth)
