摘要

通过熔盐反应法成功合成了原位TiB

/A356铝基复合材料

研究了不同增强体含量对复合材料组织与性能的影响。结果表明

随着TiB

颗粒含量增加

复合材料的晶粒尺寸逐渐降低。复合材料的强度随着增强体含量的增加而升高

而伸长率则表现出逐渐降低的趋势。利用改进的剪切-滞后模型对复合材料的屈服强度进行了预测

结果表明

该模型较好地反映了TiB

/A356铝基复合材料的强度变化。

Abstract

In-situ TiB

/A356 composites were synthesized by the molten salt reaction method

and the influence of different reinforcement contents on the structure and properties of TiB

/A356 composites were investigated. The results indicate that the grain size of the composites is gradually decreased with the increasing content of TiB

particles. The strength is increased with the increasing content of the reinforcement

while the elongation is gradually decreased.The yield strength of the composite was predicted by the improved shear-hysteresis model

indicating that the calculated yield strength variation can be well fitted with the experimental values of the TiB

/A356 composites.
