Annealing Fe-P-Mn and Fe-P-Mn-V soft-magnetic amorphous alloys prepared fro
m ferrophosphorus waste leads to the formation of fine-particle crystalline
phases. The associated structural hardening is more pronounced in alloys w
ith stronger interatomic interactions. The dissolution of Mn and V inhibits
the growth of Fe3P particles, which became smaller than the alpha -Fe part
icles.
