A STUDY OF METALLURGICAL EFFECTS IN HIGH VELOCITY DEFORMATION OF COPPER USING ROTARY EXTRUDED LINERS

Abstract

Rotary extruded shaped charge liners have been investigated to determine the effects of preferred orientation on the optimum spin compensation frequency. The tangential component of collapse velocity obtained in rotary extruded liners is produced by a tangential shear in the liner wall which is induced by crystallographic slip in individual grains. The value of spin compensation frequency which is obtained is therefore dependent on the orientation of grains in the liner wall, which in turn is sharply dependent on the original condition of the blank and the changes in various manufacturing parameters. Because of the dependence of this frequency on grain orientation it is possible to determine the optimum spin compensation frequency by measurements on a normal incidence X-ray diffraction pattern. Such measurements form the basis for a non-destructive test for this type of liner.
