Abstract
The effects of carbon and chromium and of the kind of heat treatment on the structure and properties of high-chromium cast iron (HCCI) is investigated. The methods of x-ray spectral and metallographic analysis are used to determine the mechanical properties and wear resistance of HCCI. It is shown that it is necessary to provide an austenitic structure of the metallic matrix by hardening from 1150°C in still air in order to obtain maximum strength, impact toughness, and wear resistance of the metal. A high-temperature hold (1150°C) provides rounding of the sharp edges of the segregating carbides, which promotes additional enhancement of the combination of the properties.
