The nitrides of most of the group IVb-Vb-VIb transition metals (TiN, ZrN, HfN, VN, NbN, TaN,
MoN, WN) constitute the unique category of conductive ceramics. Having substantial …

Over the past decades, enormous effort has been dedicated to enhancing the hardness of
refractory ceramic materials. Typically, however, an increase in hardness is accompanied by …

Simultaneously hard and tough nitride ceramics open new venues for a variety of advanced
applications. To produce such materials, attention is focused on the development of high …

We use density functional theory calculations to explore the effects of alloying cubic TiN and
VN with transition metals M= Nb, Ta, Mo or W at 50% concentrations. The ternary systems …

Recently, transition metal nitrides received attention as potential alternative materials for
plasmonics due to their high electron conductivity and mobility, high melting point, chemical …

High-entropy ceramic coatings have some unique physical and mechanical properties, such
as high hardness, good corrosion resistance and excellent thermal stability. However, since …

Obtaining high hardness combined with enhanced toughness represents one of the current
challenges in material design of hard ceramic protective coatings. In this work, we combine …

In this work, we comparatively study the phase formation, stress development, thermal
stability and oxidation resistance of two ternary transition metal nitride systems, namely Ti–Zr …

Solid solution strengthening enhances hardness of metals by introducing solute atoms to
create local distortions in base crystal lattice, which impedes dislocation motion and plastic …

Abstract (TiZrNbTa) N x films were fabricated at various nitrogen flow ratios (R N2) through
reactive direct current magnetron co-sputtering. The structural, mechanical, and …
