Cerium in aluminum alloys
TL;DR: In this paper, the role of cerium in forming stable, highmelting-point compounds, improving strength and thermal stability is analyzed along with its function as a grain refiner in the aluminum melt, the eutectic modifier, as de-gasifying and de-slagging agent through its reaction with gas and liquid impurities.

Estimation of Debye temperatures by averaging elastic coefficients
TL;DR: In this paper, the elastic debye temperatures were calculated by averaging elastic stiffness coefficients, and eight averaging methods were evaluated with respect to a computationally exact θ. Reuss's θ, corresponding to uniform stress, gave better agreement than Voigt's and Hill's geometrical θ gave the best agreement.

Structural and electronic properties of Os B 2 : A hard metallic material
TL;DR: In this article, the structural and electronic properties of Os-B were calculated using density functional theory with or without taking into account the spin-orbit (SO) interaction, and the results showed that the bulk modulus with and without SO interactions are 364 and $365\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}, respectively, both are in good agreement with experiment $(365--395\phantastic{\rule} 0.3m/πa)/πa), respectively.
