Abstract: Uniaxial compressive properties of hybrid Mg/Al-CNT nano-composites are studied in the present paper. Hybrid nano-composites were fabricated using powder metallurgy route followed by microwave assisted rapid sintering technique and hot extrusion. The hybrid Mg/Al-CNT nano-composites exhibited slightly smaller grain sizes compared to monolithic Mg and reasonable hybrid Al-CNT nano-particle distribution up to Al content of 1.00 wt%. Compared to pure Mg, the Mg/Al-CNT nano-composites exhibited higher compressive yield strength (0.2% CYS), ultimate compressive strength (UCS) and work of fracture (WOF) (up to +36%, +76%, +36%) compared to pure Mg but failure strain was compromised. Inclusive of crystallographic texture changes, the effect of hybrid Al-CNT nano-particle integration on the enhancement of compressive properties of Mg is investigated in this paper. © 2011 Springer Science+Business Media, LLC.
