Strength characteristic in aluminium alloy / copper alloy dissimilar materials joint plate produced by friction stir welding and rolling

Abstract

In order to realize a new structure and function, direct joining method of dissimilar materials has been studied. According to previous results, friction stir welding (FSW) is possible to make dissimilar materials joint such as steel and aluminum alloy, copper alloy and aluminum alloy, etc.. It is expected to add various functions like composite materials by joining materials with different properties. The present research work aims to develop a thin dissimilar materials joint plate produced with rolling process followed by FSW between aluminum alloy and various metallic materials. In this report, effect of rolling process on strength characteristics under static and cyclic loading condition in a dissimilar materials FSW joint between copper and aluminum alloy is shown.
