Research on Rheological Characteristic of Molten Al and Al Alloy through Stirring Torque

    摘要
  • 摘要: 从理论分析将牛顿定律中剪切应力和剪切速率的关系转换为搅拌扭矩和转速的关系,并通过实验进行验证,理论推导和实验的结果非常吻合,此方法可以用来判断熔体的流变特性,也可以间接衡量增粘过程的效果。

     

    Abstract: The relation between the shear stress and shear rate in the Newtonian law was shown by the relation between the stirring torque and revolution through the theoretical analysis. By means of the relation between the stirring torque and the revoludon,not only the rheological characteristic of the molten A1 alloy can be identified, but also the effect of the increasing viscosity can be determined. The method for the producing porous A1 can be conveniently controlled.
