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 ...

Characterization of high-quality MgB2(0001) epitaxial films on Mg(0001)

, 2005
High-grade MgB2(0001) films were grown on Mg(0001) by means of ultra-high-vacuum molecular beam epitaxy. Low energy electron diffraction and x-ray diffraction data indicate that thick films are formed by epitaxially oriented grains with MgB2 bulk ...

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.

Many-Beam Solution to the Phase Problem in Crystallography

, 2008
Solving crystal structures from electron diffraction patterns rather than X-ray diffraction data is hampered by multiple scattering of the fast electrons within even very thin samples and the difficulty of obtaining diffraction data at a resolution high ...
