Volume is indexed by Thomson Reuters BCI (WoS).Strength and ductility are two of the most important mechanical properties of structural materials, but this usually involves a trade-off, because of the fundamental inverse proportionality of these two features. Since the 1980s, bulk nanostructured materials have emerged as a new class of material having unusual structures and, as a result, have attracted increasing attention. Unfortunately, most bulk nanostructured materials still do not evade the strength-ductility trade-off dilemma, and usually have very poor ductility. The poor ductility of bulk nanostructured materials has indeed become a seemingly insurmountable obstacle to the widespread technological application of structural bulk nanostructured materials.
