Abstract A criterion of the formation of amorphous state alloys by melt quenching has been proposed as I/ΔS<0.032 and (Ⅰ—0.1)/Δ>0.0044, where Ⅰ=1—T_m/T_m and S=1/100C_B((?)_m-T_m), T_m=melting point of the alloy, (?)_m=weighted average melting points of its components and C_B=at% of solute B. However, this criterion seems to be more accurate since special account has been taken of the effects of alloy composition and intermediate phase. All 127 alloys with one exception only checked up well with the criterion. Furthermore, the concentration distribution of the amorphous alloys and the characteristics of the allied constitution diagrams have been discussed.
