Abstract A new type of torque meter was successfully used to measure the viscosity of the
Al alloy in the foaming process. The real time measurement and control of the
viscosity were achieved in the preparation process of Al and Al alloy, revealing
the rule of viscosity change as well as the influence on pore structure. The viscosity
change with time is similar to the growth curve. The greater viscosity value decreases
the pore diameters and increases the number, while less viscosity value is on the
contrary. The optimized viscosity value in the foamed process of Al alloy is
27$\sim$28 mN$\cdot$m in this experiment.
