Composition dependence of viscosity for Al(1? x )Mgx(0? x ?0.10) alloys
Composition dependence of viscosity for Al(1-x)Mgx(0≤x≤0.10) alloys

Viscosities of molten Al(1 x)Mgx (0 x 0.10) alloys have been measured in the temperature range of 973 K-1173 K by a torsional oscillation cup method. The viscosity dependence on temperature for Al(1 x)Mgx (0 x 0.10) melts obeys Arrhenius equation. The viscosity increases with increasing magnesium concentration in the investigated system. There is an important relationship between viscosity and its glass-forming ability for metallic melt. Supported by the National Natural Science Foundation of China (Grant Nos. 50231040 and 50171037)
