While some superior properties of nanostructured materials(with structural scales below 100 nm)have at- tracted numerous interests of material scientists,technique development for synthesizing nanostructured metals and alloys in 3-dimensional(3D)bulk forms is still challenging despite of extensive investigations over decades. Here we report a novel synthesis technique for bulk nanostructured metals based on plastic deformation at high Zener-Hollomon parameters(high strain rates or low temperatures),i.e.,dynamic plastic deformation(DPD). The basic concept behind this approach will be addressed together with a few examples to demonstrate the capability and characteristics of this method.Perspectives and future developments of this technique will be highlighted.
