| Abstract Scope |
Since its development nearly thirty years ago, Friction Stir Welding (FSW) has revolutionized the joining of metals — in particular, the solid-state process allows for the successful welding of lightweight materials. For example, FSW makes possible the joining of dissimilar lightweight metals such as aluminum and magnesium. Nevertheless, aluminum-magnesium welds are weakened by the formation and compaction of intermetallic compounds (IMCs). In this article, the dispersion of IMCs and resulting tensile strength are examined for different parameters of FSW lap welds between aluminum-5052 and magnesium-AZ31b. We plan to test resulting joints for quality in several ways: tensile testing; scanning electron microscopy (SEM) imaging for IMC production; hardness testing; and X-ray diffraction (XRD) spectroscopy. |
