It was found that in the early stage of ag-ing, a metastable R phase precipitated in both Fe-Cr-Mo and Fe-Cr-W alloys,which transformed to stable μ-phase, Laves-phase, X-phase or σ-phase in the laterstage. The crystallographic structure of metastable R phase is rhombohedral withlattice parameters α=0.9075nm, α=74.45°. The chemical composition of metastableR phase is Fe-(27.5--34.9)Mo-(0--25.5)Cr and Fe--(28.9--33.0)W--(9.36--21.0) Crin at.-% in Fe-Cr-Mo and Fe-Cr-W system, respectively.
