Nitrogen in Steels IspatGuru

May 23, 2013 · Recently, it was noticed that nitrogen has significant effect on mechanical properties, phase stability, corrosion behaviour and oxidation resistance. Nitrogen can also react with titanium and aluminum in liquid steel and generate nitride inclusions, which can damage the surface of the steel and decrease the quality of the final product. Reconciling multiple impacts of nitrogen enrichment on Impacts of reactive nitrogen (N) inputs on ecosystem carbon (C) dynamics are highly variable, and the underlying mechanisms remain unclear. Here, we proposed a new conceptual framework that integrates plant, microbial and geochemical mechanisms to reconcile diverse and contrasting impacts of N on soil C.
