An innovative magnetic oxide dispersion-strengthened iron compound obtained from an industrial byproduct, with a view to circular economy

摘要: Abstract Since the policy of Sustainable Production and Consumption has laid basis for world to begin its transition towards a circular economy, engineering moral responsibility recycle industrial byproducts. This is currently done with calamine, which mill scale resulting from high temperature steel manufacturing. Although calamine used in different ways, it could be given greater added value by subjecting processing powder metallurgy. Therefore, aim this study was obtain iron core enriched magnetite oxide, evaluate effect oxide nucleus on hardness magnetic properties material after sintering. It found that acts as reinforcement (the highest achieved 77.7 ± 1.2 HRB) due, part, coherency between phases, confers ferrimagnetic behavior it. potential use applications at higher frequencies than current soft materials.
