Fabrication and Mechanical Properties of AlSi12 Nano Particulate Composite

Nano-particulate composite AlSi12 with Single, Double and Multi walled Carbon Nanotubes (SWCNTs, DWCNTs & MWCNTs) as reinforcement at 0.5% by weight are fabricated using powder metallurgy process. Powder Metallurgy test specimens were prepared according to ASTM B-925 standards and specimens were tested for Tensile strength and Hardness. It is observed that AlSi12 reinforced with 0.5 weight percentage of SWCNTs, DWCNTs & MWCNTs has shown improvement in tensile strength and hardness when compared with pure AlSi12 alloy. In this work an attempt also made to test energy dispersive X-ray spectroscopy (EDS) and thermogravimetric analysis of nano particulate composite samples.
