摘要: 用可液淬取样的同轴双筒粘度仪,研究了Sn-Pb共晶合金在切变流动中的凝固组织和流变性质。结果表明:切变凝固的共晶组织是由粒状组织单元构成的,单元内有三种不同形态的共晶区域。凝固中的合金浆粒具有非牛顿流体的流动性质。

Abstract: The microstructures and rheological features of partially solidified eutectic Sn-Pb alloy were studied shear flows using a concentric cylinder viscometer (Searle-type). It is found that the alloy has its structure of the sphercidal particles which could be composed of three colonies different in the eutectic morphology, and that the slurry flows with the properties of a non-Newtonian fluid.
