摩擦搅拌接合方法及接合体
摘要：
本发明的实施方式涉及的摩擦搅拌接合方法中，相对于由第1金属部件、主元素与所述第1金属部件所含的主元素相同的第2金属部件、和夹在所述第1金属部件的至少一部分与所述第2金属部件的至少一部分之间且主元素与所述第1金属部件及所述第2金属部件所含的主元素相同、粒径为20μm以下的第3金属部件构成的被接合部件，一边使前端具有突起的工具旋转一边向所述被接合部件按压，从而将所述第1金属部件、所述第2金属部件和所述第3金属部件接合。
摘要（英）：

The invention relates to a friction-stir welding method. A joined body is formed by a first metal part, a main element, and a second metal part having the same main element as the first metal part, and a third metal part, which is clamped between at least a part of the first metal part and at least a part of the second metal part, and has the same main element as the first metal part and the second metal part, and has a particle size smaller than 20(mu)m. A tool having a protrusion on a front end is rotated, and the joined body is pressed, and therefore the first metal part, the second metal part, and the third metal part are joined together.
