PLASTIC DEFORMATION METHOD FOR SHAPING MATERIAL BY USING IMPACT PRESSURE OF LIQUID

摘要

K-24-1776OM/77 A plastic deformation method utilizes a high shock pressure in a liquid medium provided in one side of a workpiece, the other side being faced to a solid member, to push the workpiece to a surface of the solid member to thereby deform the workpiece along the surface. The shock pressure is produced by bombarding the liquid medium with a pellet accelerated to a velocity in a range from several hundred to several thousand m/sec.
