摘要
通过对TiB2颗粒增强铝基复合材料熔体粘度的系统测量和分析,研究了TiB2颗粒增强铝基复合材料熔体的粘度随温度变化的规律和熔体结构的变化。结果表明TiB2颗粒增强铝基复合材料熔体的粘度随温度的变化呈明显的不连续性,根据粘度的变化可以将熔体状态分为高温区、中温区和低温区,各温区间存在粘度突变温度点。在低温区和中温区之间可能存在着由TiB2引起的熔体结构的变化。
The rule of viscosity dependent on temperature and the structure changes for molt of aluminum matrix composites reinforced by TiB2 particle has been studied by the systematic measurement and analysis.The results show that the change of viscosity with temperature for the melt is significant discontinuities.According to changes in viscosity the melt state can be divided into high temperature zone,intermediate temperature zone and low temperature zone,to exit the temperature points of viscosity mutation in each temperature interval.There may be some changes in structure of molt caused by the TiB2 between the low temperature zone and intermediate temperature zone.
