A Study of the Oxygen Activity Before Start of Solidification of Cast Irons

Mostrar todas las versiones(2)

In the present paper the oxygen balance during a temperature decrease and especially at temperatures close to the liquidus temperature has been studied for lamellar, compacted and nodular cast irons. Extrapolated data from the full scale trial results show that there are significant differences in t...
