Abstract
Experiments were conducted to acquire Hugoniot data for Ti6-Al-4V at compressive stresses up to 250 GPa for use as a standard material on the three-stage gun at Sandia. Ti-6Al-4V was chosen over several other standards because in previous work on the three-stage gun it was most readily launched intact and flat. In each experiment, a graded-density launch plate travelling at 6.3 or 6.7 km/s launches a Ti-6Al-4V flier plate to 9.8 or 10.4 km/s. The flier impacts a stationary target disk of Ti-6Al-4V. Shorting pins and optical fibers imbedded in the target serve as time-of-arrival sensors to determine the shock velocity. These also permit quantification of the bow and tilt of the flier plate, which are found to be comparable to shots on two-stage guns. Corrections are made for the temperature of the flier in order to calculate the stress and particle velocity behind the shock.
