Elastic Properties of Uranium - .78 Titanium as a Function of Pressure to 1.6 GPa

Abstract:

The transit time for passage of longitudinal and shear ultrasonic waves through polycrystalline depleted uranium - .78 weight percent titanium Ti alloy was determined as a function of pressure in a hydrostatic medium. Specimens of two thicknesses were used in order to eliminate bond-transducer effects from transit time determinations. The longitudinal velocity vL increases 3.5 percent from one atmosphere to a value of 3.48 kmsec at 1.6 GPa the shear velocity vs increases 5 percent to 2.08 kmsec the adiabatic bulk modulus Bs increases 8.1 percent to a value of 120 GPa and the shear modulus u, 9.4 percent to 81 GPa over the same pressure range.
