A displacement wave has been observed in a plastically deforming aluminum-alloy sample under a tensile load. The observed wave indicates a recently proposed mechanism concerning how deformation evolves to fracture. The estimated phase velocity of 110 mm/min is three orders of magnitude higher than the tensile speed.
