Designing sustainable high-entropy alloys directly from mixed oxides: A thermodynamic perspective
Albert Linda, Shiv Shankar, Dierk Raabe
Hydrogen-based direct reduction (HyDR) of mixed oxide precursors offers an alternative route to produce sustainable alloys, bypassing the sequential extraction, refining, and remel…
Mechanistic insights into hydrogen reduction of multicomponent oxides via in-situ high-energy X-ray diffraction
Shiv Shankar, Barak Ratzker, Claudio Pistidda +2
Co-reduction of multicomponent oxides with hydrogen provides a carbon-neutral approach toward sustainable alloy design. Herein, we investigate the hydrogen-based direct reduction,…
Domain Boundaries in a Metallic Distortive Polar Metal
Adrian Savovici, Barak Ratzker, Xuyang Zhou +12
Polar metals are an underexplored material class combining two properties that are typically incompatible, namely a polar crystal structure and reasonable electrical conductivity.…
Sustainable Pre-reduction of Ferromanganese Oxides with Hydrogen: Heating Rate-Dependent Reduction Pathways and Microstructure Evolution
Anurag Bajpai, Barak Ratzker, Shiv Shankar +2
The reduction of ferromanganese ores into metallic feedstock is an energy-intensive process with substantial carbon emissions, necessitating sustainable alternatives. Hydrogen-base…
Hydrogen-based direct reduction of multicomponent oxides: Insights from powder and pre-sintered precursors toward sustainable alloy design
Shiv Shankar, Barak Ratzker, Yan Ma +1
The co-reduction of metal oxide mixtures using hydrogen as a reductant in conjunction with compaction and sintering of the evolving metallic blends offers a promising alternative t…
A physics-encoded Fourier neural operator approach for surrogate modeling of divergence-free stress fields in solids
Mohammad S. Khorrami, Pawan Goyal, Jaber R. Mianroodi +3
The purpose of the current work is the development of a so-called physics-encoded Fourier neural operator (PeFNO) for surrogate modeling of the quasi-static equilibrium stress fiel…
