METHOD FOR PRODUCING METAL MEMBER
First Claim
1. A method for producing a metal member, comprising the steps of:
- preparing a first member made of a first metal and a second member made of a second metal having a smaller deformation resistance than the first metal; and
joining the first member and the second member,the step of joining the first member and the second member including steps ofheating the first member and the second member by relatively rotating the first member and the second member with respect to each other about an axis of rotation, while pressing the first member and the second member against each other, without changing a relative positional relationship between the first member and the second member, the first member having a surface serving as a first contact surface coming into contact with the second member, the first contact surface having a recess formed therein so as to include a region intersecting the axis of rotation, andcooling the first member and the second member heated, with the members being pressed against each other.

Abstract
The method includes a step of preparing a first member made of a first metal and a second member made of a second metal having a smaller deformation resistance than the first metal, and a step of joining the first member and the second member. The step of joining includes a step of heating the first member and the second member by relatively rotating the first member and the second member, while pressing the first member and the second member against each other, without changing a relative positional relationship therebetween, and a step of cooling the first member and the second member heated, while being pressed against each other. In a first contact surface which is a surface of the first member coming into contact with the second member, a recess is formed so as to include a region intersecting the axis of rotation.
