Influence of Manganese Content on the Dissolution of theFe3CIron Carbide Phase (Cementite) during a Graphitization Anneal of Spheroidal Graphite Cast Iron

摘要

The transformation of iron carbide cementite was investigated on spheroidal graphite containing different contents of manganese. The isothermal maintain were carried out at 600, 650, 700, and 750°C for periods of up to one hour. It was observed that the kinetics of graphitization is slowed even more than cast iron rich in manganese.
