Influence of the Structure of Fe–Si–Mg–Rare Earth Modifiers on the Production of Compacted Graphite Iron for Camshafts

Resumo

The structure of a modifier in two forms (ingot and chip) for the production of compacted graphite iron (also known as vermicular graphite iron) is investigated by means of an electron microscope and also by X-ray microspectral analysis. The possibility of qualitative identification of the phase composition and surface macroanalysis of the modifier particles is considered.
