Co-V Fe-Fe is a chemical compound consisting of two molecules of iron atoms joined together with vanadium. This alloy is used for electrical generators in aircraft. The magnetic properties of the alloy depend on the grain size and distribution of precipitates.

Typical Fe-Co-V alloys contain 0.4-1.4% Ti, 0.5-1% Al, and 0-10% Ni. These alloys have long range order, high strength, and good to excellent ductility at room temperature. They also have a high energy efficiency under fluctuating DC conditions. In addition, they exhibit high resistance to oxidation.

Fe-Co-V alloys are commonly used in applications with high saturation magnetization. However, they are prone to undesirable DC magnetic properties when the base metal exceeds 2 wt. %. Adding vanadium to the alloy reduces eddy current losses and increases the resistivity of the alloy.

Unlike conventional soft magnetic alloys, Fe-Co-V alloys have a high yield strength. Their high resistance to oxidation and low eddy current loss make them an ideal choice for applications with high saturation magnetization.

Fe-Co-V alloys have been shown to have superior room temperature ductility in an ordered state. This feature has led to their use in pole tips of high field magnets. A variety of applications have been successfully performed on Fe-Co-V alloys, including electric motors, aircraft electrical generators, and magnetostatic coils.

The invention describes a series of experimental variations on prior art Fe-Co-V alloys. Each sample exhibits a different effect on the microstructure and/or the mechanical properties.
