摘要： A friction stir tool is provided to perform friction stir riveting using a partially consumable pin, wherein the pin includes a cutting edge on a bottom surface thereof, wherein the tool is rotated at a first speed to enable cutting by the pin into a first material that is overlapping a second material, wherein after the pin has cut to a sufficient depth, the rotational speed of the tool is increased to thereby enable plasticization of the consumable pin, the first material, and the second material, wherein the tool is then rapidly decelerated until stopped, enabling diffusion bonding between the pin, the first material and the second material.

摘要翻译： 提供摩擦搅拌工具以使用部分可消耗的销执行摩擦搅拌铆接，其中销包括位于其底表面上的切削刃，其中该工具以第一速度旋转以使得能够被销切割成第一材料， 与第二材料重叠，其中在所述销已切割到足够深度之后，所述工具的旋转速度增加，从而能够使所述可消耗销，所述第一材料和所述第二材料塑化，其中所述工具随后迅速减速 直到停止，使得销，第一材料和第二材料之间的扩散结合成为可能。
