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。
Apparent viscosity of TiB_2 particle reinforced aluminum matrix composites melt with varied TiB_2 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 750~780℃ 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 780~830℃ as a result of particle deposition.
