Part of the solidification of Al-10% Cu alloy rheological behavior


u of the curve shown in Figure 4. Figure 4 under different cooling rate curves similar pattern , with the solid fraction increases, the apparent viscosity of an uptrend , but the contrast performance of different cooling rate viscosity values ​​can be found (see Figure 5 ), high cooling rate Slightly higher apparent viscosity . The results with the literature [4 ] based Bong similar. D ¨ m ● -. Sun = (85 Mindanao :, , 3 laps of a section of Southeast University +66 22 mixing head diameter of 3.3 Experimental results show that under isothermal conditions in the continuous cooling, the smaller diameter of the first measure of the apparent mixing High viscosity . According to the liquid mixing theory. stirrer shear rate not only with the greatest speed , but also with diameter of the mixing head , a large mixing head can have a greater shear rate . For our device , stirring head diameter The larger head and shaking stirred crucible smaller the gap , the higher average shear rate . These two factors make large mixing head slightly lower apparent viscosity measured . 【 a) a 2 × loK / s , D a 65m] won four one ● 1.19r / s ▲ 2.3Bf, s ● 3.57r/s2dI24 conclusions. 】 s'; ● V - 1.
