Abstract The effect of minor boron addition on tensile properties of wrought Ti-47Al-2Mn-2Nb alloy was investigated at strain rates from 20 to 1000s-1 , using a self-made separated Hopkinson tensile bar setup. It was found that the addition of 1.0%B (atom fraction) increases dynamic tensile strength considerably, but does not damage the linear relationship between dynamic tenisle strength and the strain rate. Meanwhile, the addition produces neither obvious improvement on dynamic tensile ductility nor noteworthy change in fracture mode.
