The Effect of Addition of CeO2 Nanoparticles on the Microstructure and Mechanical Properties of Ti-Al-Mg Compact Samples


In this research, Ti-15Al-5Mg alloy with different amount of CeO2nanoparticles was prepared by powder metallurgy method, the powders of thesematerials were mixed together by ball mill then the mixed powders werepressed under high pressure, the compacted samples were sintered in electronfurnace under argon gas. The density and porosity measured using Archimedesmethod, XRD and SEM images were used to detect phase's peaks andmicrostructure of all alloy sets. Vickers micro-hardness measured and Braziliancompressive tests, the results of these tests were drawing in charts with porosityand CeO2 nanoparticles percentage. From these results the best amount ofCeO2 is 7 vol.% which give best mechanical and physical properties, becauseof created of (Ti-CeO2)
