Abstract
In this work, Ni-15%Al alloy with additives of CeO2 prepared by powder metallurgy method, Nickel and Aluminum Powders were tacking blending and mixing as (Ni-15%Al) then adding CeO2 powder for different percentage after the mixture was compacting and sintering, then measuring the density and porosity for it. Microstructure analysis by microscope and x-ray diffraction tests which done. Finally we discuss the effect of additives percent on the properties of alloy. We found that there was no significant enhancing in hardness with increasing of additives percent, in spite of; were resistance increased with increasing of additives percent.
Key word: composite material, Ni-Al alloy.
