binary system, phase diagram, miscibility gap, spinodal decomposition, nucleation and growth.Abstract
Spinodal decomposition is a phase separation mechanism within the miscibility gap. Its importance in
case of binary system, this work is aimed at a better understanding of the phase separation process in the binary
system. Fully ferritic microstructured alloys was observed that hardness of homogenized samples increased
monotonically with increasing one of metal content up to 55 wt.% which can be attributed to solution hardening
[1]. However, it means that alloys are suffering phase separation. For compositions inside the miscibility gap,
hardening effect is a result of phase separation either by nucleation and growth or spinodal decomposition [3].
According to the previous studies, the spinodal boundary is most probably located in this composition range.
However, no change in hardness was observed even up to 24h.Further investigations are needed to confirm and
explain this result
