Web10 jun. 2015 · June 10, 2015 by George Vander Voort. Abstract. Metallographic techniques for cast irons are similar to those for steels; with the exception that graphite retention is a more challenging task. Recommended procedures to prepare cast irons are given. Colloidal silica is an excellent final polishing abrasive for many metals and alloys. WebThe final microstructure will be quite similar to ductile cast iron. Like ductile cast iron the matrix is the continuous phase and so the final structure will have similar properties to ductile cast iron, excellent strength, ductility, and toughness.
