is the theory of the characteristic crystals and points out direction of alloy design. The theory has been successfully applied to Ag–Cu alloys [1, 2] and Au–Cu alloys [3–6] in FCC structure, Ti–Al... J. Cent. South Univ. (2018) 25: 1573-1581 DOI: https://doi.org/10.1007/s11771-018-3849-x Derivation and application of concentration formula of alloy genes of DO3-type in BCC alloy systems PENG......
, and the stability of the intermetallic phases are investigated in Fe-Cr-W-Co-Si system. The precipitates of the Si-free Fe-10Cr-1.4W-4.5Co (at%) alloy aged at 873K are the R-phase but those of the Si-added Fe-10Cr-1.4W-4.5Co-0.3Si (at%) alloy are the icosahedral quasicrystalline phase. The precipitates in both the Si-free and Si-added alloys aged at 973K are the Laves phase. Matrix of the alloys......
