The temperature cycle imposed on the parts during their presence in the furnace involves changes in the microstructure of the constituent material as well as its composition.
The microstructure developed during sintering determines the physical and mechanical properties of the material [7, 8]. 3.
The total porosity in the sintered materials depends on their density, according to formula (2), [7].

Materials and components at nano-scales have some noticeable properties, such as extremely high rigidity and intensity.
Nanometer is at the scale of atoms, and the interactions among atoms show decisive influence on the behavior of nanometer materials at this scale, so nanometer materials must be analyzed as materials with certain atomic configurations and atomic potentials, but not a simple continuum.

Finally, a Cr2O3 oxide film with lower diffusion velocity, formed on the material surface, greatly reduced the diffusion rates of Fe and other alloying elements, playing a protective role on the materials.
With this surface shot peening process, the materials with peening strength of 0.25-0.35A and 200% surface coverage could be obtained.
Eventually the Cr2O3 oxide film with a lower diffusion rate was formed in the material surface, which greatly reduced the diffusion rates of Fe and other alloy elements, thus playing a protective role on the materials.
