Building the Nano composites for getting material with combinational properties and improving properties of currently used material has been taken significant attention. One of the ways of building Nano composites is using a method known as powder metallurgy. Because with this method not only wastes are decreased to minimum but we can also mix the materials with high melting point with the materials with low melting point which is a difficult thing to do with foundry method. In this research titanium alloy for improvement in its mechanical properties is mixed with silicon carbide reinforcing. Knowing the fact that silicon carbide is in Nano scale these two materials start building Nano composites. The powder metallurgy method is the best way for mixing these two materials together. To make sure that the properties of the made alloy is similar to the foundry alloy, the static compression methods are used. For comparison the results, two factors such as the Nano silicon carbide percentage and the static compression pressure are. Also, Density experiment, observation of grain boundaries using a scanning electron microscope, pressure test and the hardness experiment was done on it.
