摘要：Adopting cyclic superheating and DSC analysis, solidification behavior of undercooled Fe50Cu50 alloy was investigated. When the melt is undercooled below a certain temperature depending on the alloy composition, the homogeneous liquid was separated into two phases, Fe-rich L-1 and Cu-rich L-2, once the melt was undercooled below a liquid-phase separation temperature T-sep. If the duration from T-sep to T-s1 (solidification temperature of L-1 phase), termed the liquid-phase separation interval Delta(t), the Delta(t) is more long so the phase separation degree is various.
