Title:
COMPOSITE METAL MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/063185
Kind Code:
A1
Abstract:
Provided is a technology whereby different types of material are appropriately arranged and a composite metal material having desired characteristics can be produced in a short time by extrusion. The production method comprises: an intermediate material creation step in which a core material is inserted inside a cylindrical tube material and an intermediate material is created; and a composite metal material production step in which the created intermediate material is extruded and a tube material and a core material and/or core materials are composited to produce a composite metal material. The core material inserted inside the tube material comprises a plurality of core materials and the cross-sectional shape of the plurality of core materials and the cross-sectional dimensions are the same for all. At least one core material among the plurality of core materials is a different type of material from the tube material. A composite metal material having the desired characteristics is produced by adjusting the combination of tube material and plurality of core materials, creating the intermediate material, and then extruding same.
