Effect of additional Multi-Walled Carbon Nanotubes on characteristic of Ti-24Nb-4Zr-8Sn alloy
Abstract
Due to its higher specific strength, superior corrosion resistance, and low density, titanium (Ti) and its alloys have found widespread application in petrochemical, aerospace, biomedical, and several other manufacturing. Throughout the years, Because of their exceptional qualities, carbon nanotubes have received attention in engineering materials research due to their outstanding and excellent properties. Owing to the demands for lightweight materials with extraordinary mechanical and thermal properties for diverse. The purpose of this study is to evaluate the effects of various percentages of multiwall carbon nanotubes(MWCNT) (0.1%, 0.2%, 0.3%, 0.4%) addition to Ti-24Nb-4Zr-8Sn(Ti2448) on phase compositions and macrostructures also mechanical properties such as wear resistance and hardness of Ti-24Nb-4Zr-8Sn- MWCNT composites fabricated by the powder metallurgy. Experimental results demonstrate the hardness increases with increases percentage of MWCNT reaching 172 HB with when addition of 0.4%, while the grain size and wet wear rate decreased with increasing the content of MWCNT reaching 23.7µm and 7.034*10-5 respectively.
