“…Such processes are able to produce long length SPD-ed products in the form of strips, rods and wires, which shows their potential to adapt to the existing manufacturing environments. Another limitation of the SPD-ed products is loss of ductility mainly due to saturated work hardening [19,20].…”

This paper reports the microstructure evolution, mechanical properties and strengthening mechanisms of a commercial purity Al alloy (Al 1350) after severe plastic deformation by a novel continuous method called ‘Equal Channel Angular Torsion Drawing (ECATD)’. Electron backscatter diffraction (EBSD) results revealed an inhomogeneous grain refinement including a large fraction of low-angle grain boundaries. After four passes, the microhardness increases from the initial value of 35 HV up to 44 and 62 HV at the centre and near to wire surface, respectively. A combination of high strength and ductility can be achieved based on the results of a Taguchi design of experiment (DoE) for mechanical properties. The strengthening occurs due to increment of the dislocation density, and development of mainly new low-angle grain boundaries.

With the day by day increasing use of nanomaterials based products for different applications, it becomes very much important to devise methods which can produce nanomaterials with desired properties and in considerable amount. To meet these requirements, one should have precise knowledge about different methods that can be used for synthesis of nanomaterials. The first part of the chapter will be focusing on basics of nanotechnology along with the properties that generate so much interest in their study. Then different approaches and methods employed for synthesising nanomaterials will be discussed. Different physical methods like mechanical milling, sputtering, laser ablation, lithography etc. that are used for the synthesis of nanomaterials will also be discussed. Different chemical methods like co-precipitation, chemical vapour deposition (CVD), chemical reduction, microemulsion, laser pyrolysis, thermal decomposition, sonoelectrodeposition, solvothermal & hydrothermal, microwave assisted synthesis, sol gel method etc. with a focus on how to apply them, will also be discussed.
