Nanocrystals produced by megaplastic deformation of the amorphous state (type IV nanocrystals)

Extreme effects have a significant impact on the structure and properties of solids [1]. These should certainly include the impact of very large plastic deformations. Over the last years the interest in this method of processing materials increased significantly, as it gives the opportunity to significantly improve the physical and mechanical properties of metallic materials. [2] This is largely due to the formation of nanostructured states of different types and, in particular, the processes for nanocrystallisation in processing of meltquenched amorphous alloys.
