Effect of Extrusion Process on Mechanical Properties of Al-MWCNT Composites Synthesized by Powder Metallurgy Route
摘要
Powder Metallurgy (PM) technique was employed in this study to synthesis aluminum reinforced with multi-walled carbon nano-tube (Al-MWCNT) composites. Composites are fabricated by varying CNT as 0.33, 0.66, and 0.99 wt.%. And the fabricated Al-MWCNT composites were extruded at 500 °C. Based on experimental results it was found an increase in ultimate tensile strength, yield strength, compression strength and hardness by 26.6%, 15.92%, 114.55%, and 36%, respectively at 0.99 wt.% MWCNT composites compared to pure aluminum. Scanning electron microscopy images shows the uniform distribution of MWCNT in the aluminum matrix.
