Paper Title:
Characterization of Friction Stir Welded Joints in TA15 Titanium Alloy Plates
  Abstract

Friction stir welding (FSW) was applied to TA15 titanium alloy plates. Welds were produced by employing rotational speed of 375rpm and a travel speed of 23.5mm/min.The microstructure and mechanical properties of friction stir welded joints were investigated. Flow pattern of the materials also were analysed. The stir zone (SZ) was characterized by α-phase and β-phase, but the size of the grain in the middle of the SZ was much finer than that of the upper. The interface between the base metal (BM) and SZ is associated with the flow state of the plastic materials. Results of transverse tensile test indicated that all the joints exhibited lower tensile strength than the BM, and the maximum tensile strength of the as-welded joint is about 97.6% of the average strength of the BM.
