Abstract

This contribution shed light on the effect of the tool positioning on the
microstructure and the mechanical properties of dissimilar friction stir welds
between a high-Mn austenitic TRIP steel and a commercial HSLA steel
produced using a tool rotational speed of 500 rpm and a welding speed of 100
mm/min. The results showed that an increased tool displacement towards the
TRIP steel increased the welding penetration and diminished the hardened stir
zone of both steels and the heat-affected zone which evolved on the HSLA
side. This also led to a slightly larger ductility of the butt-joints. A reduction of
the heat input by decreasing the tool rotational speed or the welding speed
combined to a tool offset larger than 2 mm towards the TRIP steel appears to
lead to optimum joining parameters.
