抄録
A supersaturated Cu-26Ni-8Fe alloy was deformed by cold rolling and the changes occurring on annealing at 750°C have been follovred by hardness testing and optical and electron microscopy observation. It was found that a modulated structure formed prior to recrystallization of a supersaturated solid solution. In the case of the heavily deformed sample, the iron nickel-rich phases grow anywhere including grain boundaries or deformation bands, and the recrystallization can start in the area free of the modulated structure around the coagulated iron nickel-rich phases. Therefore, the recrystallized structure consists of fine equiaxed copper-rich and iron nickel-rich grains termed as the microduplex structure. The structure has a good strength and ductility at room temperature. The structure also has a suitable high temperature stability and so appears capable of undergoing superplastic deformation at 750°C. The strain rate sensitivity index of flow stress m of about 0.5 was obtained and the specimen maintained a relatively fine equiaxed grain structure even after large elongation at 750°C.
