METHOD FOR MANUFACTURING METAL-BASED MODIFIED PLATE MEMBER

WIPO Patent Application WO/2021/241318

A1

The present disclosure provides a method for simply manufacturing a metal-based modified plate member having superior quality at a lower cost, without being affected by the machining precision of end surfaces of metal-based plate members to be abutted. A method for manufacturing a metal-based modified plate member according to the present invention comprises: a step A for setting a first end surface and a second end surface of metal-based plate members so as to be opposing each other with an interval therebetween, and thereby providing a gap between the first end surface and the second end surface; a step B for inserting a filler, heated to at least the melting point thereof, into the gap to fill the gap, or filling the gap with the filler and heating the filler to at least the recrystallization temperature, and then causing the filler to conform to the shapes of the first end surface and the second end surface to thereby from a filled section in which the gap is filled with the filler; and a step C for inserting, into at least the filled section, at least the probe of a friction stirring/rotating tool having the probe, and modifying at least the filled section from among the metal-based plate members and the filled section by implementing friction stir processing (FSP), and thereby obtaining a metal-based modified plate member provided with an FSP section.
