Abstract
In the present study, a Fe-Cr-C hypereutectic alloy was prepared from industry-grade materials
and subjected to modification and fluctuation, through which new types of particle reinforced composites,
hypereutectic in-situ composite, was generated. The structures of the composite modified or not with the
range of fluctuation addition from 0% to 2.8wt.%, were investigated. The primary carbides were refined
with the addition of modifying agents and fluctuations. Increasing the amount of fluctuation resulted in
finer primary carbides. At 1380oC, with the addition of modifying agents and 2.8wt.% fluctuation
addition, the structure was well modified.
