TY - JOUR A1 - Coniglio, Nicolas A1 - Cross, Carl Edward T1 - Characterization of solidification path for Aluminium 6060 weld metal with variable 4043 filler dilution JF - Welding in the world N2 - Aluminium alloy 6060 is typical of a family of Al-Mg-Si extrusion alloys, which are considered weldable only when using an appropriate filler alloy such as 4043 (Al-5Si) or 5356 (Al-5Mg). This study concerns the thermal analysis and solidification path determination of aluminium alloy 6060 diluted with variable amounts of 4043. Casting of controlled mixtures of alloys 6060 and 4043 was used to simulate different weld dilutions in order to facilitate thermal analysis. Thermal analysis and metallography were applied in order to reveal solidification reactions and phases, and allow calculation of solid fraction versus temperature curves. Although the liquidus temperature was little affected, different phases formed with increased 4043 dilution, with a trend toward lower temperature reactions and a larger fraction interdendritic constituent.
