Seminar Dr. Alexander Zhilyaev: Bulk nanostructured materials processed by severe plastic deformation: from fundamentals towards applications

In recent years, the development of bulk nanostructured materials (BNM) has become one of the most fascinating directions in modern materials science. One method of nanostructuring is the “top-down” approach which is based on grain refinement through heavy straining or shock wave loading. During the last two decades, grain refinement by severe plastic deformation (SPD) techniques has attracted special interest since it offers new opportunities for developing different technologies for the fabrication of commercial nanostructured metals and alloys for various specific applications. Very significant progress was made in this area in recent years.
The generation of new and unusual properties has been demonstrated for a wide range of different metals and alloys: examples include very high strength and ductility, record-breaking fatigue endurance, increased superplastic forming capabilities as well as multifunctional behavior when materials exhibit enhanced functional (electric, magnetic, corrosion, etc.) and mechanical properties. The innovation potential of this research area is exceptional and now a transition from laboratory-scale research to industrial applications is starting to emerge (Valiev RZ, Zhilyaev AP, Langdon TG.
