Abstract

Abstract Fatigue crack propagation (FCP) tests were conducted using the dissimilar joints between Al alloy and steel fabricated by friction stir welding. CT specimens were sampled from the friction-stir-welded plates so that the initial notch was consistent with the interface. Crack closure during FCP was measured by a back-face strain gauge. The FCP rates of the welds were slower than those of Al parent metal. Crack opening points of the welds were higher than that of the parent metal. FCP rates were nearly the same among all the samples, when FCP rates were estimated by the effective stress intensity factor range.
