【 摘 要 】

In present work, the effects of hybridizing micron sized B4C particles with multi walled carbon nanotubes on the microstructural and mechanical properties of Al - B4C composite were investigated. Microstructure reveals grain refinement ascribed to the presence of uniformly distributed micron sized B4C particles with multi walled carbon nanotubes. The Al - (B4C + MWCNT) hybrid composite indicates the alliance of mechanical properties such as hardness, tensile strength and ductility. The enhanced attribute of Al - (B4C + MWCNT) hybrid composite when compared to Al - B4C is the increased content and uniform distribution of MWCNTs.
