抄録

Mössbauer experiments are performed on Si-rich Fe–Co–Si alloys. New information on their phase separation process, from the as-quenched state to that of the DO3+ε phases, is obtained. Analysis of the Mössbauer spectra is made based on the preferential site occupation rules. The phase boundary and the tie-line are accurately determined. The chemical order of the rapidly quenched specimen is shown to be complete inside the DO3 phase boundary, while it is incomplete outside unless annealed. The degree of the chemical order of Co atoms is determined.
