In this work, Ti‐6Al‐4V alloy was jointed by linear friction welding (LFW). A sound weld of thickness about 65–115 μm was obtained under the present processing parameters. The weld consisted of a superfine α + β microstructure, which is associated with the quick heating and cooling processes involved in LFW. This superfine microstructure contributes to the higher hardnesses of weld (422 ± 11Hv 0.2 ) than that of parent Ti‐6Al‐4V (302 ± 20 Hv 0.2 ). The tensile properties of weld are comparable to or higher than those of parent Ti‐6Al‐4V.
