Recrystallization in a spinodal Cu-Ni-Fe alloy

The interaction of spinodal decomposition and recrystallization process, and the characteristic of recrystallization in Cu-Ni-Fe alloy aged at different temperatures after solution-treatment and cold rolling have been studied by structural analysis and Vickers hardness test. It has shown that the recrystallization of spinodal Cu -Ni-Fe alloy might be divided into 2 types: spinodal decomposition, recovery and recrystallization of two-phase microstructure take place in the deformed alloy aged below the spinodal temperature; while recrystallization of single-phase microstructure and growth of fully-recrystallized grains take place in the deformed alloy aged above the spinodal temperature. The deformed alloy aged below the spinodal temperature recrystallizes in cellular morphology.
