FRICTION STIR WELDING TOOL MEMBER AND FRICTION STIR WELDING DEVICE USING SAME, AND FRICTION STIR WELDING METHOD
The friction stir welding tool member according to the present invention is characterized by comprising a ceramic member in which a shoulder part and a probe are integrally formed, wherein a base section of the probe part and the end of the shoulder part both have a curved surface shape, and when a curvature radius of the end of the shoulder part is defined as R1 (mm) and the outer diameter of the shoulder is defined as D (mm), R1/D is 0.02-0.20. In addition, the ceramic member is preferably made of a silicon nitride sintered compact having a Vickers hardness of at least 1400HV1. According to this configuration, the present invention is able to provide a friction stir welding tool member that has excellent durability.
