Effect of Silicon and Vanadium on the Composition of Carbide Phase in Mottled Medium-Alloy Chromium-Nickel Cast Iron.

Medium-alloy chromium-nickel cast iron with different contents of silicon and vanadium is studied. The composition of the carbide phase, the distribution of elements in the carbide phase and in the metallic matrix, and the proportion of the structural components and of the carbides are determined. The effect of the form of globular graphite on the mechanical properties of the cast iron is described. Acomposition for fabrication of wear resistant parts with a mass exceeding 100 kg is suggested.
