Microstructure - Wikipedia
Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification. The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low ...

Metallography - an overview | ScienceDirect Topics
Cast iron is commonly adopted as a lap material because of its low cost and consistent accuracy on the lap surface. According to metallography, cast iron is a type of polycrystal metal, consisting of hard pearlite iron, soft ferrite iron, and free carbon. Such pearlite iron has a layered microstructure with the hard cementite and soft ferrite ...

CAST IRON is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentiation from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min 2.03%) that ensures the solidification of the final phase with a eutectic transformation. Depending on chemical specifications, cast irons can be nonalloyed or ...

Metallography of cast iron insight | Struers.com
Cast irons are ferrous alloys with mostly 2.5-4 % carbon and 1-3 % silicon. The main difficulty in the metallographic preparation of cast iron is to retain the true shape and size of the graphite in its flake, nodular or tempered form. In particular, cast irons with a soft ferritic matrix tend to smear and are prone to deformation and scratching.
