High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

open access: yesAdvanced 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

open access: yesAdvanced 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.

Crystal‐Symmetry‐Driven Build Orientation and its Impact on the {110}<100> Goss Texture Formation and Mechanical Properties of Laser Powder Bed Fused AISI 316L

open access: yesAdvanced 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,

Thermal Conductivity of Silicone Rubber Composites: Effects of Ceramic Fillers, Pressure, and Temperature

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the influence of ceramic fillers—aluminum oxide, boron nitride, and a combination of aluminum oxide and zinc oxide—with different particle sizes, on the thermal conductivity of solid silicone rubber. Additionally, the impact of potential synergistic interactions from the simultaneous addition of selected fillers is explored to ...

Carboniferous algaflora in the Urals and its stratigrafical meaning

open access: yesЛитосфера, 2016
In the Urals Carboniferous 11 algae zones allowing to make interregional and intercontinental correlation of coeval deposits are established by author. For more fractional dividing of carbonate profiles on algoflora for the first time akmezones have been
