摘要：
The authors studied effect of cerium and lanthanum on crystallization parameters anti structure formationof cast iron.It was found that REM additives increased duration and temperature range of eutectic transforma-tion and prevented primary graphite precipitation.The change in crystallization pattern of iron is due to theREM effect on graphite nucleation and growth.On the basis of microprobe analysis of REM distribution and theDTA results,a mechanism of the REM effect on iron crystallization and graphite morphology was suggested.
