Abstract: To provide a manufacturing method of an aluminum alloy member in which characteristics is locally modified.SOLUTION: The present invention relates to the manufacturing method of an aluminum alloy member having a modified portion different in the characteristics from the surrounding portion in a base material made of an aluminum alloy. Specifically, a first electrode (1) made of a first metal and a second electrode (2) made of a second metal are energized therebetween while the first electrode (1) and the second electrode (2) are brought into pressurized contact with a local portion of a base material (W). Thus, a modification step of forming a modified portion in a joule-heated local portion is performed. According to the manufacturing method of the present invention, the first metal constituting the first electrode and the second metal constituting the second electrode are set to be larger in the electric conductivity than the aluminum alloy constituting the base material. Thus, the local portion is rapidly heated efficiently, and can be heated to the temperature needed to change the characteristics (metallurgical texture) in a very short time. Thus, an aluminum alloy member having a modified portion where only the local characteristics is modified can be efficiently obtained.SELECTED DRAWING: Figure 1
