Synthesis, analysis and deformation of co-sputtered multilayers of amorphous CuZr and nanocrystalline Cu — •Farnaz Abdollahzadeh Davani, Sven Hilke, Martin Peterlechner, and Gerhard Wilde — Materials Physics, Münster,Germany

Metallic glasses are of scientific and technical interest due to their high strength and hardness. Upon deformation, it is expected that soft spots deform locally, finally leading to localized shear in so-called shear bands. In this work, multi-layers of amorphous CuZr and nanocrystalline Cu have been prepared by magnetron co-sputtering of pure Zr and Cu. The as processed structures were analyzed using scanning electron microscopy and transmission electron microscopy. Upon deformation of the layered system, the deformation can be analyzed in the crystalline and amorphous regions. The processing and the deformation are discussed.
