Modeling of spatial distribution of the eutectic M 2B borides in Fe-Cr-B cast irons

, 2004
The spatial distribution of the eutectic M B borides in Fe-Cr-B cast irons was predicted using strain models. The spatial distribution of the eutectic M B borides was revealed by scanning electron microscopy (SEM) using deep-etched specimens.
