摘要：

In this paper the critical cooling rate, Rc, for the glass formation of Fe80P13C7 alloy has been determined using both Uhlmann’s and Barandiaran-Colmenero’s method. In Uhlmann’s method, all kinds of the expressions of △Gl-s (T) and η (T) determined using the different modes and methods had been investigated. It is indicated that the R c for the glass formation of Fe80P13C7 alloy can be estimated to be 349 K/s by Uhlmann’s method based on the appropriate expressions of △Gl-s (T) and η (T). The calculated result accords with our experimental result. The R c for the glass formation of Fe80P13C7 alloy has also been determined to be 0.49 K/s using Barandiaran-Colmenero’s method. This resultant R c is unreasonable low and it indicates that Barandiaran-Colmenero’s method does not suit to Fe-based alloy.
