On the role of liquid phase stability and GFA parameters

Role of liquid phase stability on the glass forming ability (GFA) has been reviewed and the alloy systems have been analyzed by introducing a contribution factor (wg) to the characteristic temperature Tg, in the γ parameter. The kinetics of glass formation for various alloy systems has been found to vary with liquid phase stability in metastable state. The GFA of a fragile liquid is found to be more responsive to the contribution of metastable stability compared to strong liquid.
