The factors of the atomic size difference Delta and the enthalpy of mixing Δ H mix of the multi‐component alloys were summarized from the literatures. The formation zones of solid‐solution phases, intermediate phases, and bulk metallic glasses were determined and the validity was verified by experimental results. For forming the solid solution, the alloys should have high entropy of mixing, lower Delta, and not too negative and positive enthalpy of mixing.
