%X 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.
