Abstract

Ingots of three FeCo alloys, Fe-70 at % Co, e-50 at % Co and Fe-30% Co, were successfully extruded at 1000°C, then re-extruded at 750°C in order to produce fine-grained material. The resulting microstructures were examined both optically and by transmission electron microscopy. It was found that increasing the Fe: Co ratio produces less complete recrystallization: Fe-70 at % Co was completely recrystallized even after both the 1000 and 750°C extrusions, whilst Fe-30 at % Co was partially recrstallized after the 1000 °C extrusion. Single dislocations were present in the extruded alloys except single-extruded Fe-30 at % Co, in which dislocation pairs were observed.
