Elastic properties and plastic deformation of TiC- and VC-based pseudobinary alloys

Synthesis and characterization of multicomponent (CrNbTaTiW)C films for increased hardness and corrosion resistance

“…group 6 elements leads to an increased covalent character in the bonding [38]. The VEC was also calculated for our film and found to be in the range of 8.0-8.4 which is at the "sweet spot" of the hardest carbide [42,43].…”

“…The (111) surface of cubic carbides with a B1 structure is polar and typically exhibits a higher surface energy than the (001) surface [38]. At 300°C, the films exhibit a typical columnar microstructure 30-50 nm wide, where each column consists of a single grain extending from the substrate to the film surface.…”

Temperature-dependent elastic properties of binary and multicomponent high-entropy refractory carbides

“…Poisson's ratio recalculated using EH and B from ref. [39] in formula  = [1-EH/(3B)]/2. w [101], ab initio calculations.…”

“…For the two high-entropy carbides (HEC), synthesized as single-phase B1 materials [36][37][38], we also evaluate the room-temperature elastic moduli from sound velocity measurements that allow us to verify the reliability of AIMD results. We note that the (Ti,Zr,Hf,Ta,W)C system exhibits particularly high hardness [36], while (V,Nb,Ta,Mo,W)C is of interest because of its relatively high valence electron concentration, which may improve ductility [9,39].…”

Tuning structure and mechanical properties of Ta-C coatings by N-alloying and vacancy population

“…Nevertheless, to intrinsically reduce brittle behavior of thin film materials the prevalent bonding character is of major interest. Several studies have considered alloying on the metallic sublattice and hence tailoring the electronic structure 15 , 16 . For examples, Kindlund et al .…”
