Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

How a Fee Per-Unit Garbage Affects Aggregate Recycling in a Model with Heterogeneous Households [PDF]

This paper develops a utility maximizing model of household choice among garbage disposal, recycling, and littering. The impact of a user fee for garbage collection is modelled for heterogeneous households with different preferences for recycling.

Interaction of MgO Recyclate‐Based Cermet Anode With KF‐AlF3‐Al2O3 at 800°C During Laboratory Scale Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
A carbon‐free, as‐sintered MgO–steel cermet anode, fabricated via cold isostatic pressing using MgO–C refractory recyclate, was evaluated under laboratory‐scale K‐cryolite electrolysis at 800°C. Operation at this reduced temperature, combined with the electrolyte's limited electrical conductivity, led to an increase in cell voltage.

Approaching fully equiaxial grains of Er/Zr modified selective laser melted Al–Mg–Mn alloys

Journal of Materials Research and Technology
In this study, high-strength Al-8.5Mg-0.78Mn-0.96Er-1.94Zr alloys are prepared by selective laser melting(SLM). The microstructure and mechanical properties of the Al–Mg–Mn–Er–Zr alloys in the as-built and heat-treated states are investigated.
