Texture Analysis of Nanostructured Metals Produced by Severe Plastic Deformation

Abstract:

In the present work the processes of crystallographic texture formation during severe plastic deformation (SPD), which has been carried out in the conditions of high imposed pressures (up to 6 GPa) and extremely large cumulative deformation degree (e up to 1÷100 and more) in pure metals, are investigated. It is shown that the processes of nanostructure formation as a result of SPD are accompanied not only by known processes such as a fragmentation, extension of misorientation angles, character modification of dislocation density, but also by the formation of deformation textures. The deformation textures, having been formed as a result of SPD are analyzed for the examples of FCC Cu, BCC W and HPC Ti, depending on a cumulative deformation degree and SPD scheme. The obtained crystallographic texture data are used for the analysis of the nanostructured state formation regularities.
