Unveiling the Transporting Mechanism of (Ti_0.2Zr_0.2Nb_0.2Hf_0.2Ta_0.2)C at Room Temperature

Crystals, 2023
High-entropy materials have been widely researched in recent years, and more work on their thermal and electrical properties is still needed. Herein, we fabricate a high-entropy carbide (Ti0.2Zr0.2Nb0.2Hf0.2Ta0.2)C ceramic and report the thermal and ...

Exploring alloying effect on phase stability and mechanical properties ofγ″-Ni3Nb precipitates with first-principles calculations

Materials & Design, 2020
The superior mechanical strength of Inconel 718 and similar Nb containing alloys mainly results from the ordered γ″-Ni3Nb precipitates. By employing first-principles calculations, we comprehensively investigate the effects of alloying elements (i.e., Sc,

Marine Geochemistry of Zr, Hf, Nb, Ta, Mo and W [PDF]

, 2009
In geochemistry, incompatible elements are unsuitable in size and/or charge to the cation sites of minerals, and therefore concentrated in a liquid phase during the fractional crystallization of magma.
