Title:
MAGNESIUM-LITHIUM ALLOY JOINING METHOD AND JOINED BODY
Document Type and Number:
WIPO Patent Application WO/2019/031145
Kind Code:
A1
Abstract:
Provided are: a joining method which makes it possible to impart strength and plastic workability which equal or exceed that of a base material to a stirred part and is a simple and efficient friction stir welding method for cases when at least one of the materials to be joined is a magnesium-lithium alloy; and a joined body obtained by using the joining method. Further provided are: a modification method which makes it possible to impart strength and plastic workability which equal or exceed that of a base material to a desired region of a magnesium-lithium alloy; and a metal structure obtained by using the modification method. Thus, a method for friction stir welding one material to be joined and another material to be joined, the method being a metal material friction stir welding method characterized in that at least one of the materials to be joined is a magnesium-lithium alloy, and in that any friction stir welding tool from among a hard metal alloy tool, a cermet tool, a ceramic tool, an intermetallic compound tool and a ceramic-covered tool is used, and said tool is inserted from the side on which the one of the materials to be joined is located.
