摘要：
The benefits of carbon addition achieved in iron aluminides based on Fe3Al, could not be achieved in the case of iron aluminides based on FeAl because of the precipitation of soft graphite phase as against hard Fe3AlC0.5 at high concentration of carbon. This study also indicates that the strength of iron aluminides containing carbon appears to be determined by the volume fraction of Fe3AlC0.5 precipitates in these alloys.
