ABSTRACT:
Provided is a dissimilar metal joint product of nickel-titanium alloy material and pure titanium material, having a tensile strength at the joint not less than that of the pure titanium material before joining, having a small variation in the strength at the joint, and having narrow heat-affected zone after joining, and a method for joining thereof. A round rod1of the nickel-titanium alloy material is integrally joined with a round rod2of the pure titanium material, while rotating at least one of the joining faces for conducting frictional pressure welding, applying a specified upset force thereto to compress thereof, after the start of deceleration of the rotation, in a period where peripheral velocity in the outermost periphery of the rotation in the joining face is not less than 0.5 m/sec. A reaction layer structure is formed at the joint by the compressive force induced by the upset force and by the rotational force of decelerating rotation.
