Coupled segregation mechanisms of Sc, Zr and Mn at theta ' interfaces enhances the strength and thermal stability of Al-Cu alloys
Baptiste Thomas Jean Rouxel, Lu Jiang
The refinement and thermal stability of intermediate theta-prime (theta') precipitates are critical in the development of new high strength 2xxx series aluminium-copper (Al-Cu) alloys for high temperature applications. In this work, we use trace additions ...
PERGAMON-ELSEVIER SCIENCE LTD2021Freeform Microstructuring of Cast Polymer-Derived Ceramics by Sacrificial Direct Laser Writing
Jürgen Brugger, Lorenz Hagelüken
Polymer-derived ceramics are known for their resistance to high temperatures and harsh environments as well as property tunability and compatibility with various shaping techniques. We demonstrate here a new hierarchical micro-manufacturing process combini ...
2021Microstructure Selection in Laser Remelted Fe-C-Si Alloys
Wilfried Kurz, Philippe Gilgien
Laser surface remelting at various velocities has been employed to study the selection of microstructures of high-purity Fe-C-Si alloys containing nominally 3.2 to 4.2 wt.% C and 1 to 3 wt.% Si. The microstructure of the remelted region consisted of metast ...
WALTER DE GRUYTER GMBH2021Advancing industrial decarbonization by assessing the future use of renewable energies in industrial processes (AID-RES) - Decarbonizing alternatives for the European Steel Industry
The Iron and Steel Industry is one of the most carbon-intensive in the European Union, and to meet the climate agreement objectives for 2050, it must dramatically reduce its environmental footprint. The present study analyzes the potential for CO2 emission ...
2021Dosimetry modeling and experimental validation for the PETALE program in the CROCUS reactor
Andreas Pautz, Vincent Pierre Lamirand, Pavel Frajtag, Axel Guy Marie Laureau
The PETALE experimental program in the CROCUS reactor intends to provide integral measurements on reactivity worth and dosimetry measurement to constrain nuclear data relative to stainless steel heavy reflectors. The experimental setup consists in eight su ...
2021Composition and Pressure Effects on Partitioning of Ferrous Iron in Iron-Rich Lower Mantle Heterogeneities
Philippe Gillet, Marco Cantoni, James Badro, Susannah McGregor Dorfman, Farhang Nabiei, Charles-Edouard Boukaré
Both seismic observations of dense low shear velocity regions and models of magma ocean crystallization and mantle dynamics support enrichment of iron in Earth’s lowermost mantle. Physical properties of iron-rich lower mantle heterogeneities in the modern ...
2021Tensile response of Ultra High Performance PE Fiber Reinforced Concretes (PE-UHPFRC) under imposed shrinkage deformations
Emmanuel Denarié, Mohamed Abdul Hafiz, Amir Hajiesmaeili
PE-UHPFRC is a new Ultra High-Performance Fiber Reinforced Concrete (UHPFRC), which is developed to reduce the environmental impact of conventional UHPFRC by replacing the steel fibers with synthetic ones and reducing the clinker content in the mix. The de ...
2021Shape Optimization of Soft Magnetic Composites using Level-set Method
Yves Perriard, Adrien Jean-Michel Thabuis, Xiaotao Ren
Soft Magnetic Composites (SMCs) possess promising electromagnetic characteristics and attract intense research and application interest in the engineering community. Fabrication of composites with customized architecture is feasible due to the recent advan ...
2021Bi-stable spin-crossover in charge-neutral [Fe(R-ptp)(2)] (ptp=2-(1H-pyrazol-1-yl)-6-(1H-tetrazol-5-yl)pyridine) complexes
Bi-stable charge-neutral iron(II) spin-crossover (SCO) complexes are a class of switchable molecular materials proposed for molecule-based switching and memory applications. In this study, we report on the SCO behavior of a series of iron(II) complexes com ...
2020Iron sequestration by transferrin 1 mediates nutritional immunity in Drosophila melanogaster
Bruno Lemaitre, Jean Philippe Boquete, Igor Iatsenko, Alice Marra, Jasquelin Peña
Iron sequestration is a recognized innate immune mechanism against invading pathogens mediated by iron-binding proteins called transferrins. Despite many studies on antimicrobial activity of transferrins in vitro, their specific in vivo functions are poorl ...
