RECRYSTALLIZATION IN A SPINODAL Cu  Ni  Fe ALLOY

Abstract

Abstract: Theinteraction ofspinodaldecomposition and recrystallization process,andthecharacteristic ofrecrystallizationin Cu Ni Fe alloy aged atdifferenttemperaturesaftersolution treatmentandcold rolling have been studied by structural analysis and Vickers hardnesstest. It has shownthat the recrystallization of spinodal Cu Ni Fe alloy might be divided into 2 types:spinodal decomposition, recovery and recrystallization oftwo phase microstructuretook placein the deformed alloy aged below thespinodaltemperature; whilerecrystallization ofsingle phase microstructureand growth offullyrecrystallized grainstook placeinthedeformed al loy aged abovethespinodaltemperature .The deformed alloyaged below thespinodaltemper aturerecrystallizedin cellular morphology.

Key words: spinodaldecomposition, recrystallization , cellular morphology
