Abstract

The 50 pet Fe-50 pet Co alloy undergoes a transformation from disorder to an ordered structure of the CsCl type reportedly in the vicinity of 732°C. During this process, the coercive force goes through a maximum, apparently as a result of strains associated with the coherent nucleation and growth reaction. This magnetic alloy also shows a marked increase in the ratio of residual to saturation induction, which is associated with annealing to a high degree of order with the continuous application of a magnetic field. The increase in ratio can be explained on the basis of a decrease in 90° domain boundaries and, perhaps, by an increase in anisotropy resulting from lattice distortion.
