Abstract

A white cast iron of composition Fe81C14Si5 can be cast into a nanostructure with network morphology by a fluxing technique. The conventional morphology of white cast iron, which is brittle, is eutectic. The mechanical behavior of network white cast iron is attractive. Hardness tests indicate that its average hardness value is ∼770 HV. The indentations made during hardness tests have no cracks. A stylus surface profiler was employed to study the surface profile at and near the indentations. The studies indicate that there are severe plastic flows, but without cracks.
