Abstract

It was shown that the liquid impact at the projectile speed of 1500 m/s affects a target similarly to an explosive deposited on the workpiece surface. A setup to investigate material deformation using the liquid impact was designed and constructed. The setup entailed a launcher for the acceleration of projectiles, a female die, a device for measuring the projectile momentum at the impact zone and a fixture for fastening the launcher and the die. The experiments included punching, stamping, extrusion, and forging, Special attention has been paid to the study of the microscale forging and extrusion. Forming of steel, spring steel, brass, aluminum, and copper samples was investigated. Dimensional stability and surface topography of the samples generated in the course of performed experiments were examined. The feasibility and effectiveness of the application of liquid impact for metal forming were shown.
