Description
An experimental procedure based on a Gleeble 3500 thermomechanical testing system was developed to investigate hot deformation parameters in the high temperature range for application to friction welding related processes. Experiments were conducted with respect to rotary friction welding of bar specimens of S355J2C+C structural steel (0.18%C, 1.33%Mn, 0.05%Cr, 0.04%Ni, 0.01%Mo, 0.01%V, 0.02%Al, 0.03%Cu). The testing programme incorporated tensile tests allowing for arbitrary temperature profiles, and the temperature dependent power law exponent and its corresponding flow stress values were determined. The welding process was simulated using an in-house finite element code. The relevance of the results for friction stir welding is discussed.
