Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, Volume 97, Issue 5, Page 2541-2558, May 2026.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...
