Bulk And Graded Nanometals: Proceedings Of Symposium G, European Materials Research (Solid State Phenomena)

In recent years, bulk and graded nanometals have attracted the growing interest of materials scientists. Nanometals can be obtained by using various methods: gas condensation or ball-milling with subsequent consolidation, thermal spray techniques, annealing of thin amorphous ribbons and severe plastic deformation. The plastic deformation methods include severe torsional straining under high pressures, equal channel angular pressing, cyclic extrusion compression - and others. The increasing practical applications of nanostructured metals, or of metals with nanostructured coatings, make it even more important to carry out basic research in the field: including characterisation, microstructural transformation mechanisms, and modelling studies; with particular attention being paid to deformation mechanisms. Multi-scale analysis is required for treating those properties which depend upon the homogeneity of the microstructure, surface characteristics and - in particular - the geometries and properties of grain boundaries. The aim of this book is to provide a timely review of the latest methods for obtaining bulk and graded nanometals, and for controlling their microstructures and physical properties; with particular regard to mechanical properties.
