Effect of Bimodal-Sized Hybrid TiC–CNT Reinforcement on the Mechanical Properties and Coefficient of Thermal Expansion of Aluminium Matrix Composites

Aluminium (Al) matrix reinforced with carbon nanotubes (CNT), micron-sized titanium carbide (TiC) particles, and bimodal (nano + micron) hybrid TiC–CNT is fabricated by solution ball milling, followed by cold compaction and vacuum sintering to improve the mechanical properties and reduce thermal expansion. The hardness, wear resistance, compressive strength and CTE of pure Al, 0.6 wt% CNT/Al, 10 wt% TiC/Al, and hybrid 10–0.6 wt% TiC–CNT/Al...
