Abstract

Carbon steel is one of the most widely used materials in the industry. This material is used not only in many of the water and steam-pressure containing systems in power plants but also in the supports for these systems. Carbon nanotubes have a vast amount of applications in the fields of materials, electronics, field emission, biology, medicine, and electrochemistry. This project to study carbon nanotube steel using multi-wall carbon nanotubes (MWCNTs) powder, focusing on mechanical properties alter and microstructure. Sample preparation will involved powder metallurgy method where mixing of pure ferrite powder with MWCNTs powder and binder. Three(3) different sample weight percentages of multi-wall carbon nanotubes ( MWCNTs ) (0wt.%, 0.025wt. % and 0.075wt.%) and two (2) sintering temperature, (900 ºC and 1000 ºC) as the variable. Then, the sample will compacted to form green bodies. Sample will be sintered in the furnace to form dense body. Mechanical testing that been carried out are Macro-Rockwell hardness, X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Macro-Rockwell hardness test use to determine hardness of carbon nanotubes steel, X-Ray Diffraction use to analysis the phases in the sample and scanning electron microscope (SEM) for microstructure analysis.
