摘要

采用旋转柱体法研究了TiB2颗粒增强铝基复合材料熔体的表观粘度随温度的变化。结果表明

由于温度升高和转子的搅拌

陶瓷颗粒的分布变得均匀

熔体粘度在750～780℃时产生第一次不连续变化;之后颗粒沉降开始

熔体粘度在780～830℃温度段内开始逐渐增大。

Abstract

Apparent viscosity of TiB

particle reinforced aluminum matrix composites melt with varied TiB

volumetric fraction was tested by rotary cylinder method at different temperatures. The results show that apparent viscosity of the composites melt exhibits a different transformation at 750

80℃ as a result of more uniform distribution of the ceramic particles with increasing in temperature and rotor stirring. And then apparent viscosity of the composites melt is increased at 780

30℃ as a result of particle deposition.
