发布时间：2018-12-27 16:06
【摘要】：以水雾化法制备的Inconel713C合金粉末为原料,利用ZRZ1452型熔体流动速率仪,研究了三种塑基粘结剂体系和Inconel713C合金粉末混合制备的喂料的流变性能。通过线性回归分析,计算出非牛顿指数n和τ_w-γ_w近似关系式。结果表明:在52%装载量下,三种组分喂料的粘度均随温度的升高以及剪切速率的增大而减小。粘结剂组成为85%POM+5%HDPE+10%其他助剂的喂料(D1)具有最好的充模性,呈假塑性流体。喂料D1的粘度与温度关系更好地符合Arrhenius定律,随剪切速率的增加,粘流活化能降低,而指前因子增大。
[Abstract]:The rheological properties of three kinds of plastic-based binder and Inconel713C alloy powder were studied by using ZRZ1452 melt flow rate meter and Inconel713C alloy powder prepared by water atomization method as raw material. By linear regression analysis, the approximate relations of non-Newtonian exponent n and 蟿 _ w- 纬 _ w are calculated. The results showed that the viscosity of the three fractions decreased with the increase of temperature and shear rate at 52% loading. The feed (D1) with 10% 85%POM 5%HDPE as binder has the best filling property and is pseudoplastic fluid. The relationship between viscosity and temperature of feed D1 obeys Arrhenius's law better. With the increase of shear rate, the activation energy of viscous flow decreases and the preexponential factor increases.
