| Abstract Scope |
In this work we present first direct experimental evidence of single step manufacturing process to produce gears via an innovative In-situ friction stir forging (I-FSF) process. The I-FSF process is robust and viable for wide range of non-ferrous materials and fabricating complex designed forged product. We successfully demonstrated manufacturing of 8 and 14 teeth spur gears and 6 teeth fin gears in this work. A thermomechanical smoothed particle hydrodynamics (SPH) model was developed to simulate in-situ friction stir forged 14 teeth spur gear to understand material flow pattern radially and through thickness in gear teeth. The plastic strain distribution and temperature profile were also simulated using the SPH model. EBSD analysis exhibits directional material flow pattern due to forging action and formation of dynamically recrystallized grains across radial, through thickness direction. The flow pattern determined using imaging, and temperatures measured were in good agreement with the corresponding SPH simulation results |
