Abstract

See full text

A gradient control method for a microstructure ultrafine crystallization of a deep cone copper shaped charge liner includes the steps of an extrusion forming, a recrystallization heat treatment, and a high-frequency percussion. A multi-pass extrusion is used in the extrusion forming, and in the high-frequency percussion step, a percussion speed is 30,000 to 40,000 times/min, a percussion force is 1600 N to 2000 N, and a number of percussion times is 1 to 3. The forming and surface quality control of the deep cone shaped charge liner are realized by the control technology of the present invention; the plasticity of the material is improved, and fine crystal structures are obtained; and an ultrafine grain gradient structure distributed along the thickness direction is formed in the inner surface of the shaped charge liner.
