Abstract
To produce cast iron powder containing of fine-grained graphite particles, powder mixture of cast iron and graphite, which the graphite powder with various contents mixed to the cast iron turning chips, was mechanically alloyed for various milling times by high energy ball mill. The iron powder, which was contained high carbon, obtained by milling for long time. Heat treatment of the mechanically alloyed powder was carried out at various temperatures. The graphite phase with fine grain size forms in the iron matrix by the heat treatment at 1273K.
