用拉伸Split Hopkinson bar实验装置研究了SiC_p/6061Al复合材料及其基体合金的动态拉伸实验，研究了材料的应变速率敏感性。结果表明，SiC_p/6061Al复合材料及其基体合金均具有明显的应变速率效应，且复合材料的应变速率敏感性高于基体合金的应变速率敏感性。根据位错机制对此进行了解释。 |

A dynamic tensile experiment for a SiC_p/6061Al composite and its matrix alloy in an over-aged state was performed using split Hopkinson bar apparatus, and a study was made on the strain rate sensitivity of their tensile properties. Results show that SiC_p/6061Al composite and its matrix alloy exhibit an obvious strain rate effect of strength and fracture strain, and the strain rate sensitivity of the SiC_p/6061Al composite is higher than that of the 6061Al alloy. The high strain rate sensitivity of the SiC_p/6061Al composite is considered to be originated from the high dislocation accumulation rate during dynamic deformation and the constraint of SiC particles on the surrounding matrix, which dramatically enhances strain rate of the matrix. |
