摘要：

The dissimilar welds between aluminium (Al) alloy, A6061-T6, and stainless steel, type 304, were fabricated by a friction stir welding (FSW) technique. The FSW tool was offset to Al side and the probe was inserted only into Al plate. The softening occurred in Al side due to the heat input during FSW, while the hardness increased by the post-ageing treatment. Tensile strength of dissimilar weld also increased about 8.5% by the post-ageing. The residual stresses were measured based on the cos alpha method. The residual stresses parallel to the weld line, sigma(xr), were predominantly tensile, while those perpendicular to the weld line, sigma(yr), were compressive. Post-ageing treatment had little effect on the residual stresses.
