Fundamentals and Application of High Pressure Forming.

Abstract

The superposition of a hydrostatic pressure of sufficient magnitude during the deformation of a material can have a significant effect on its deformability characteristics. This effect is in the form of the pressure enhancement of ductility. How pressure effects ductility, the material and structure sensitivity of the phenomena, and the mechanisms by which it occurs are presented. The pressure enhancement in ductility has formed the basis for a new family of forming processes based upon the use of a superimposed hydrostatic pressure. The principals behind these processes and their advantages along with various applications and/or proposed applications are described. Important in any forming application, is the structural integrity of the product. The effects of cold hydrostatic deformation on mechanical properties and its use to actually enhance properties are described.
