Abstract
A metal liner for a shaped charge device having a ductile metal matrix and a discrete second phase is provided. The allow composition is selected so the second phase is molten when the liner is accelerated following detonation. The molten phase reduces the tensile strength of the matrix so that the liner slug is pulverized on striking a well casing. The slug does not penetrate the hole perforated in the well casing by the liner jet and oil flow into the well bore is not impeded. The liner is formed by directly casting the desired alloy to the desired shape.

A metal liner for a shaped charge device, consisting essentially of:
- a multiple phase alloy having a ductile metal matrix and a discrete second phase dispersed in said matrix, said second phase having a melting temperature less than the temperature reached by said metal liner following detonation of an explosive charge in said line, said metal liner cast directly to a shape effective to compress on detonation of said explosive charge.
A metal liner for a shaped charge device, consisting essentially of:
- a multiple phase alloy having a ductile metal matrix and a discrete second phase dispersed in said matrix, said second phase remaining as a precipitate dispersed in said matrix at the temperature reached by said metal liner following detonation of an explosive charge in said liner, said metal liner directly cast to a shape effective to compress on detonation of said explosive charge.
