Besides, low Z materials or low atomic number of materials also may be used as alternative due to its capability to absorb radiation and tend to avoid a decay reaction that will give rise of scattered energetic particles [4].
Boeing 747 is using 68% of aluminum on structural materials [15].
Boron and nitrogen are materials that are greatly capable to absorb the EM radiation [4, 5, 19].
However, these materials are not capable enough against cumulative EM radiation.

Introduction The science and technology of materials subject to severe plastic deformation (SPD) has evolved largely during the past 30 years.
These topical areas correspond with the natural evolutionary stages of research in materials science and materials development.
These five topical areas typically evolve sequentially within the synthesis-structure-properties triad that characterizes materials science investigations.
