Cast Iron Specimen Preparation

Metallographic etchant database

Cast Irons are difficult materials to prepare properly because the graphite nodules or the graphite flakes are easily pulled out during preparation. By minimizing the sectioning damage and by starting with a modest grit size SiC paper, retaining these difficult particles can be accomplished.
