<P>Friction stir lap welding of dual phase 590 steel has been successfully performed within the A1 to A3 temperature range upon adjusting the process parameters. The microstructures and the texture have been characterized using scanning electron microscopy and electron back scattered diffraction analysis. The martensite volume fraction increases with an increasing travel speed from 100 to 300 mm/min for a constant tool rotational speed of 300 rpm. Under severe deformation and high strain rate during friction stir welding, the grain orientation < 101 > shifts toward the < 111 > and < 001 > directions compared to the base metal. The base metal shows gamma fiber components, whereas the friction stir welded specimen shows strong brass with weak cube fibers.</P>
