The effect of alloying on the properties of (Nb,Ti)Cr2 C15 Laves phases

The effect of composition on the ternary (NbCr2–TiCr2) C15 phase properties has been investigated, focusing upon the defect structure, elastic properties, and mechanical behavior. The C15 phase field is continuous between NbCr2–TiCr2, with a maximum phase field width of at least 7 at.% solubility. The defect mechanism is governed by anti-site constitutional defects for all alloys. Mechanically,...

First principles calculations of the effect of Pt on NiAl surface energy and the site preference of Pt

Pt-modified NiAl is widely used as a coating material in industry. In this study, the surface energies of NiAl with and without Pt are investigated using first-principles calculations. The presence of Pt in NiAl takes the surface electronic states to higher energies, resulting in an increased surface energy, which explains some of the beneficial effects of Pt on the oxidation resistance of NiAl...
