A process for making an article of manufacture from elongated strip of a soft-magnetic FeCo alloy is disclosed. The process includes a prefabrication annealing step in which the elongated strip is annealed before it is fabricated into parts. The prefabrication annealing step is carried out at a temperature that is greater than the ordering temperature of the alloy. The process further includes the step of cooling the alloy from the annealing temperature at a rate that is selected to cause substantial transformation of the disordered phase of the soft-magnetic FeCo alloy to an ordered phase thereof. An article of manufacture made by using the process is also disclosed.
