- Abstract
Steady-state friction stir welding of 2014 Al alloy has been modeled using an Eulerian formulation that considers coupled viscoplastic flow and heat transfer in the vicinity of the tool. The model equations are solved using the finite element method to determine the velocity field and temperature distribution. The simulation results indicate that the temperature distribution of friction stir welding is different at different position and the highest temperature is about 533 centigrade and less than the alloy melt point. The measured results agree well with the simulation results. With the result of velocity field and viscosity field, a criterion to divide the weld zone has been given, that is, the η0-easy-flow-zone existed near the tool pin is corresponded to the weld nugget zone, the area between the η0-easy-flow-zone and η1 –viscosity-band is corresponded to TMAZ. The model gives some useful information to improve the understanding of the mechanistic study of the friction stir welding process.
