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,…
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…
Unraveling the thermodynamics and mechanism behind the lowering of reduction temperatures in oxide mixtures
Shiv Shankar, Barak Ratzker, Alisson Kwiatkowski da Silva +5
Hydrogen-based direct reduction offers a sustainable pathway to decarbonize the metal production industry. However, stable metal oxides, like CrO, are notoriously difficult…
