Columnar grain boundaries are the weakest link in hard coatings: Insights from micro-cantilever testing with bridge notches
Yinxia Zhang, Matthias Bartosik, Steffen Brinckmann +3
The effect of columnar grain boundaries on the fracture toughness was investigated using micro-cantilever fracture testing with a bridge notch, and a unique hard coating consisting…
Enhanced fracture toughness in ceramic superlattice thin films: on the role of coherency stresses and misfit dislocations
Antonia Wagner, David Holec, Paul Heinz Mayrhofer +1
Superlattice (SL) thin films composed of refractory ceramics unite extremely high hardness and enhanced fracture toughness; a material combination often being mutually exclusive. W…
Point-defect engineering of MoN/TaN superlattice films: A first-principles and experimental study
Nikola Koutná, Rainer Hahn, Jakub Zálešák +6
Superlattice architecture represents an effective strategy to improve performance of hard protective coatings. Our model system, MoN/TaN, combines materials well-known for their hi…
New insights on the formation of supersaturated solid solutions in the Cu Cr system deformed by high pressure torsion
Andrea Bachmaier, Georg Benedikt Rathmayr, Daniel Apel +3
In the Cu Cr system, the formation of supersaturated solid solutions can be obtained by severe plastic deformation. Energy dispersive synchrotron diffraction measurements on as def…
Structural stability and thermodynamics of CrN magnetic phases from ab initio and experiment
Liangcai Zhou, David Holec, Matthias Bartosik +4
The dynamical and thermodynamic phase stabilities of the stoichiometric compound CrN including different structural and magnetic configurations are comprehensively investigated usi…
Complementary ab initio and X-ray nano-diffraction study of Ta2O5
R. Hollerweger, D. Holec, J. Paulitsch +7
Numerous different crystal structures of Ta2O5 are reported in literature. Although experimentally and computationally obtained lattice parameters and mechanical properties are in…
