Abstract:The flow tracers of material particles are considered to determine the boundary of the stirring zone in friction stir welding based on a fully coupled thermo mechanical model. The real strain tensors and temperature histories are given from the tracer movements to calculate the Zener-Hollomon parameters. The grain sizes can be then predicted by the empirical formation. The width of SZ on the top surface can increase with the increase of the rotation speed. The average grain size in SZ can be increased with the increase of the welding temperature and can be decreased with the increase of the strain rates. Both the temperature and the strain rates can be obviously increased with the increase of the rotating speed. But the effect of the welding temperature is more obvious, the average grain size is increased with the increase of the rotating speed. ©, 2015, Beijing Institute of Aeronautical Materials (BIAM).
