| 中文摘要: |
| 采用高压扭转（high-pressure torsion，HPT）工艺制备SiCp/Al基复合材料，试验发现随着扭转半径的增加，剪切应变增大，SiC颗粒分布逐渐均匀；升高温度，SiC颗粒分布的均匀性好；随着扭转半径的增加材料的硬度先增加后减小，且材料越致密，SiC含量越多，分布越均匀，材料硬度越高。 |
| 英文摘要: |
| SiCp/Al composites were fabricated by high-pressure torsion. The microstructures and hardness were studied. The results show that the shear strain increases and the distribution of SiC-particles is more homogeneous with distance from the center increasing；increasing temperature is in favor of the homogeneous distribution of SiC-particles；with distance from the center increasing，the hardness increases then decreases；and the more compact the materials are，the more the volume fraction of SiC-particles is，the more homogeneous distribution of SiC-particles are, the higher the hardness of materials is. |
