摘要

本研究的目的是验证爆炸固结可以作为一种加工路线来生产金属基复合材料,包括铝基基体和碳化硼增强。在10-12 GPa的压力下,在mb85铝合金基体中成功地压缩了含有30%、50%和70%体积的碳化硼的复合材料。用透射电子显微镜检查所得的微观结构和界面质量。预测压实过程中产生的高密度位错将导致时效硬化铝合金基体的加速老化。

Shock-compacted aluminum/boron carbide composites

The aim of this study was to verify that explosive consolidation can be used as a processing route to produce metal-matrix composites, comprising an aluminum-based matrix and boron-carbide reinforcement. Composites containing 30, 50 and 70 volume percent boron carbide in an MB 85 aluminum-alloy matrix were successfully compacted at 10–12 GPa pressure. Transmission electron microscopy was used to examine the resulting microsctructure and interface quality. It is predicted that the high density of dislocations produced during the compaction will lead to accelerated aging in age-hardenable aluminum alloy matrices.
