Characteristics of graphite and cast iron particle dissolution in iron during sintering

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    The dissolution of graphite in iron may take place with the formation of a liquid phase; the temperature at which this phase appears is determined by the amount of ash impurities in the graphite.

  2. 2.

    The pearlite produced as a result of impregnation of iron with carbon forms discrete fields arranged in directions of preferential diffusion of carbon into iron rather than a continuous zone around the periphery of the impregnation source.

  3. 3.

    The appearance of a large quantity of a liquid phase accompanying the sintering of iron with a high-ash graphite is chiefly responsible for the formation of structurally free cementite.
