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.
