We study the dynamic behavior of marginal metallic glass-forming liquids Al-Ni-M (M=La, Pr, Nd) in terms of liquid fragility in high and low temperature regions. The liquids are extremely fragile above the liquidus temperature T liq , but become rather strong near the glass transition temperature T g . The strength of the transition is inversely correlated with the fragility index at T g . This relation is discussed in terms of potential energy landscape.
