| Abstrakt: |
The structure of a precipitation-hardened composite material, which consists of hard graphite inclusions coated with a two-layer ledeburite–martensite shell and uniformly distributed in a ductile metallic base, forms in the transition layer of high-strength spheroidal graphite cast iron chilled by surface quenching with melting. A process of volume heat treatment is proposed to form this structure in the volume of a product and to increase the abrasive wear resistance, the strength, and the impact toughness.
