mügardus, nodulariseerimine
promoting nodular graphite growth during solidification involving treatment with magnesium (Mg) to the molten cast iron (see: nodular graphite, ductile cast iron/nodular iron), sulamalmi töötlus (legeerimine) magneesiumiga saavutamaks mügargrafiidi (nodulaargrafiidi) moodustumine (vt mügargrafiit, keragrafiitmalm)
