The present study reports the experimental research of particle velocity increasing process generated by elastic-plastic shock waves in 6061-T6 aluminum. Planar impact experiments are carried out by a single-stage light-gas gun. The gun has 2 m long launch tube and 40 mm muzzle diameter. Projectiles are made of ABS material, and accelerated by high-pressure gas (He). Impact velocities measured by the magnet flyer method are from 227 to 413 m/sec. A target plate is hold in a target ring with 4 tilt-pins. Tilt angles obtained by any shots are from 2.4 to 3.6 mrad. The velocity changes at the rear surface of target plate are measured by the velocity interferometer system (VISAR). High-resolution data focused in the plastic shock wave are obtained, and it is shown that those data can be compared to the results of estimating simulation of the shock wave profiles.
