Fundamental knowledge of Nano-to-Atomistic Scale Deformation mechanisms in Nitride Naoncomposites

Important results from the project

The understanding of deformation mechanisms in thin films constituting self-organizing nano structures and nanolaminates is gained in this project.

Expected long term effects

We accomplished our aim in understand deformation physics as a function of temperature in perspective of grain boundary sliding/rotation mechanisms involving high density coherent/incoherent interfaces responsible for the plasticity of the complex multilayer coatings (to achieve optimum hardness, prevent crack initiation, and hinder crack propagation), and established experimental competence at LiU to study deformation mechanisms.

Approach and implementation

The scope of the project was to relate nanocomposites, grown under highly controlled magnetron sputtering conditions, to the post mechanical testing structures on an atomistic level to dig deep into deformation physics. It has been successfully realized through collaborative efforts with world leading partners at Universität des Saarland (UdS) Saarbrücken, Germany, and University of Cambridge (U.C), UK.
