The Effect of Nanostructuring on Physical and Mechanical Properties of Metallic Materials

The effect of nanostructuring on physical and mechanical properties of metallic materials is studied. It has been established that the tested samples of nanostructured metal materials exhibit the specific strength and durability enhanced by 11-32 % which at the corrosion rate less than about 11 %. In the example of titanium at 1000 K is shown that the thermal diffusivity of nanostructured metal is 1,2 times lower than in conventional polycrystalline state.
