摘要

It is deduced that the parameter of supercooled liquid fragility, m, is proportional to the product of reduced glass transition temperature, T-g/T-L (T-g is the glass transition temperature, T-L the liquidus temperature) and reciprocal of the parameter of superheated liquid fragility, 1/M, based on the definitions of the two kinds of liquid fragility and the previously studied results. The experimental result in La-and Sm-based glass-forming alloys is consistent with the deduced result. The correlation relates superheated liquid fragility with supercooled liquid fragility.
