Abstract
A bimetallic shaped-charge liner is formed by explosively bonding two metal disks and then shear-forming the bonded disks simultaneously into a conoidal shape over a mandrel. An exemplary method for manufacturing a ductile, bimetallic, shaped-charge liner comprises the steps of explosively bonding a plate of one metal to a plate of another metal; annealing the bonded plates; cuting forming blanks from the bonded, annealed plates; shear-forming the blanks with the light metal side outward into a conoidal shape over a mandrel; and then annealing the resulting conoid.
