In the current work, fine-grained dual-phase, high-entropy ceramics (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2-(Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)C with different phase ratios were prepared from powders synthesized via a boro/carbothermal reduction approach, by adjusting content of B4C and C in precursor powders. Phase compositions, densification, microstructure, mechanical properties investigated correlated. Due t...

Abstract A billet is a bar made from crude steel which surface contains scales are rich in iron oxides. This study presents the carbothermal reduction of formed billets. The process included reaction oxides contents with carbon (in ratio 5:1) and annealing tubular furnace under argon atmosphere. occurred reactions discussed using thermodynamic calculations thermal analysis indicate three-stage ...

In this work, we studied the effect of microwave treatment red mud briquettes containting more than 48% Fe on process iron reduction under various conditions heat treatment. Research samples were collected from formed during production alumina bauxite at Ural Aluminum Smelter. The chemical composition was examined by X-ray fluorescence analysis. initial and that agglomerates obtained after in m...
