Abstract
Joined structures are disclosed, which each comprise first and second members having different coefficients of thermal expansion and an intermediate member. The first and second members are joined together through the intermediate member. The intermediate member has yield stress smaller than those of the first and second members, and a tapered portion is formed at an outer peripheral surface of the intermediate member such that the tapered portion has a variable cross-sectional area orthogonal to an axis of the joined members. The area is larger at one end of the tapered portion near one of the first and second members having a smaller coefficient of thermal expansion than the area at the other end of the tapered portion near the other one of the first and second members having a larger coefficient of thermal expansion. A method of joining such first and second members having different coefficients of thermal expansion through the intermediate member is also disclosed.
