Abstract
A preparation method of a uniform low stress cone shaped charge liner includes the steps of multi-pass extrusion forming, vibration aging treatment, and cryogenic treatment. The step of multi-pass extrusion forming refers to 4 to 8 passes of extrusion deformation under the actions of a three-dimensional compressive stress and a deformation rate of 5 to 10 mm/s, having a deformation amount of 5 to 50% for each pass. The shaped charge liner prepared by the present invention has high dimensional accuracy, good geometric symmetry, low stress value, and excellent stability in the precise machining process and in use, which may significantly improve the penetration capability and stability of the shaped charge liner of high-explosive anti-tank warheads.
