In tribological applications, the degradation of metallic coatings due to oxidation and thermal
softening at high temperatures is an issue of increasing concern. Recently, researchers …

For mechanically dominated load profiles, nitrides are preferred as the base material for
structural and functional hard coatings, while oxide-based materials offer better protection …

Transition metal nitride thin films traditionally possess a low intrinsic fracture toughness.
Motivated by the recently discovered fracture toughness enhancing superlattice (SL) effect …

Motivated by density functional theory (DFT)-derived ductility indicators for face centered
cubic (fcc, rocksalt) structured TiN/MoN 0.5 superlattices and Ti 0.5 Mo 0.5 N 0.75 solid …

Abstract Single-phase crystalline (Al, Cr, Nb, Ta, Ti) O 2 high-entropy oxide thin films were
synthesized at 400° C by reactive magnetron sputtering of an equimolar Al–Cr–Nb–Ta–Ti …

Through superlattice (SL) architectures, the hardness as well as the fracture toughness of
ceramic thin films can be enhanced. The hardness-related SL effect is reasonably well …

Despite their high hardness and indentation modulus, nanostructured crystalline ceramic
thin films produced by physical vapour deposition usually lack sufficient fracture strength …

Ti–Al–N hard films are commonly applied to cutting tools to extend their lifespan. Recently,
the toughening of Ti–Al–N thin films has garnered considerable attention due to their major …

The low intrinsic fracture toughness of transition metal nitride thin films critically restrains
their applicability as protective coatings. We therefore investigate the Ti 1-x W x N y system …

Ab initio-calculated ideal strength and toughness describe the upper limits for mechanical
properties attainable in real systems and can, therefore, be used in selection criteria for …
