Quantum Potential for Diffraction and Exchange Effects
, 2009 Semi-classical methods of statistical mechanics can incorporate essential quantum effects by using effective quantum potentials. An ideal Fermi gas interacting with an impurity is represented by a classical fluid with effective electron-electron and ...

The diffraction of electrons by graphite [PDF]
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1936 The structure first attributed to graphite by Debye and Scherrer, and by Hull from X-ray powder patterns was confirmed by Hassell and Mark, by Bernal, and, finally, by Mauguin and Ott who relied mainly on single crystal X-ray photographs. The assigned structure is such that the hexagonal unit cell has the dimensions, a

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy
Advanced Engineering Materials, EarlyView.The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
Advanced Engineering Materials, EarlyView.This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Advanced Engineering Materials, EarlyView.This study explores a crystal‐symmetry‐based approach to optimize mechanical properties in laser powder bed fused AISI 316L with predominant {110}<100> Goss textures. By varying the build orientation, the microstructure can be tailored and the tensile properties optimized. The tilted build (T110) achieved the highest strength while preserving ductility,

Superconductivity in a new hexagonal high entropy alloy
, 2019 High entropy alloys (HEAs) are the new class of materials with an attractive combination of tunable mechanical and physicochemical properties. They crystallize mainly in cubic structures, however, for practical applications, HEAs with hexagonal close ...

W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications
Advanced Engineering Materials, EarlyView.This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...
