Abstract
The expansion isentropes of the explosion products of two TNT/RDX compositions (50/50 and 25/75) have been investigated. Attention is concentrated on the little-studied region of pressures below 100 kbars. Data on the expansion isentropes were obtained by measuring the shock wave parameters in various media (aluminum, plexiglas, polystyrene foam, argon, air). Points were obtained on the shock Hugoniots of argon precom-pressed to 10, 15, and 50 atm. An equation of state of the explosion products that satisfactorily describes the experimental material obtained is formulated.
