Many researches have demonstrated that the free volume have a great effect on the properties of bulk metallic glasses (BMGs). For different BMGs, however, quantitative measurement of free volumes and analysis of properties of BMGs using the measurement results are still difficult. In this work, the two types of characteristic free volumes, the free volume released in structural relaxation, ΔVf-sr and the free volume generated in glass transition, ΔVf-gt are given from the Δ(dV(T)/V0) curve, where the Δ(dV(T)/V0) is the thermal expansion difference between amorphous and crystalline samples measured by a cyclic thermal dilation test. In a series of Fe-(Er)-Cr-Mo-C-B BMGs, it is found that the BMG with the largest critical diameter (Dc) has also the largest ΔVf-gt, and Dc increases sensitively with the decrease of ΔVf-sr. More impressively, Dc2 or Dc can be fitted with high regression coefficient of 0.998 by a negative exponential function of ΔVf-sr. Hence, the characteristic free volume has a sensitive and close correlation with the glass forming ability of BMGs.
