The effect of addition of CeO2 nanoparticles on the microstructure and mechanical properties of Ti-Al-Mg compact samples

الملخص EN

In this research, Ti-15Al-5Mg alloy with different amount of CeO2 nanoparticles was prepared by powder metallurgy method, the powders of these materials were mixed together by ball mill then the mixed powders were pressed under high pressure, the compacted samples were sintered in electron furnace under argon gas.

The density and porosity measured using Archimedes method, XRD and SEM images were used to detect phase's peaks and microstructure of all alloy sets.

Vickers micro-hardness measured and Brazilian compressive tests, the results of these tests were drawing in charts with porosity and CeO2 nanoparticles percentage.

From these results the best amount of CeO2 is 7 vol.% which give best mechanical and physical properties, because of created of (Ti-CeO2).
