Novel method of severe plastic deformation for production of tubes from the Zn-4Ag-1Cu zinc alloy

Abstract

Recently, the development of innovative medical techniques for restoring lost functions of patients has been actively pursued, in which the use of bioresorbable metallic materials is of special interest. Such materials include alloys based on Mg, Fe, and Zn, and they make it possible to significantly reduce the costs of surgical operations and shorten treatment time. For example, the use of zinc alloy of increased strength will allow minimizing the size of implants that will provide less traumatism during their installation and faster dissolution in the physiological environment of the organism. It is known that severe plastic deformation is one of the modern tools for increasing the properties of metallic materials due to grain refinement of the initial structure to nano- and ultrafine range. In this paper, a new method for pressing tubes with elements of severe plastic deformation is investigated. Computer simulation by the finite element method and experiments were carried out, during which the technological features for deformation of the Zn-Ag-Cu zinc alloys were revealed.
