Influence of Manganese Content on the Dissolution of the Fe3C Iron 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.
