Abstract:
High-energy ball milling was studied for the ex situ strengthening of aluminum Al with nanodiamond ND. Al-ND metal matrix composite powders with 5 wt and 10 wt nanodiamond were synthesized by high-energy ball milling of the blended component powders. Stearic acid was used as a process control agent to minimize agglomeration of the powders upon milling. A uniform distribution of the ND reinforcement was successfully obtained after milling the powders for a period of ten hours with a ball-to-powder ratio of 301 in a SPEX 8000M ball mill. Composition and properties of the Al-ND composite was studied using energy dispersive spectrometry EDS mapping, scanning electron microscopy SEM, X-ray diffraction XRD, optical microscopy, and nanoindentation techniques
