| 摘 要： | 采用激光熔铸工艺制备多壁纳米碳管（MWNTs）增强纯铝复合材料，研究不同铸模条件和激光工艺参数对复合材料熔铸缺陷和组织结构的影响。结果表明：在相同的激光工艺条件下，石墨铸模中激光熔铸的复合材料熔铸缺陷少，组织均匀细小；在相同的激光功率和铸模条件下，扫描速度为60mm/min时，熔铸的复合材料的熔铸缺陷最少，组织最均匀细小。

| Abstract: | Aluminum matrix composite reinforced by multi- walled carbon nanotubes (MWNTs) are prepared by laser casting. The effect of processing parameters on microstructures and casting defects are investigated. The results show that microstructure of the composite prepared in graphite mold is finer and more homogeneous than that of the composite prepared in the other molds. The composite with the finest microstructure and the lest casting defects is obtained, when the laser scanning velocity is 60 mm/min and the graphite mold is chosen. |
