Investigation on Mechanical Properties of Nano Ferrous Composite

Abstract

Nowadays metal matrix composites (MMCs) find application in various fields. Metals like Aluminium, Magnesium and Nickel etc., have been mixed with Carbon Nanotubes (CNTs) as reinforcement to prepare MMCs. There exists a growing interest in CNTs reinforced metal matrix composites (MMCs) due to the fact that CNTs can serve as very good reinforcing agents for MMCs. Reinforcement of the matrix metal with CNTs leads to enhancement in mechanical properties without any considerable increase in weight of the material. In this study, 3 different samples of multi-walled carbon nanotubes (MWNTs) reinforced iron composites were fabricated by using powder metallurgy technique by mixing the powdered iron and MWNTs manually and ball milling process, compacting the specimen using a cylindrical die and then sintering it. The compaction die was designed and fabricated using die steel. The various testing like tensile, compressive, hardness and chemical were carried out and surface characteristics were analysed. The test results show that the mechanical properties were found to be improved significantly when compared to unreinforced iron.
