Beryllium has also gained attention as a “strategic, critical” engineering material [1].
China’s first High Flux Engineering Test Reactor uses beryllium as a reflective layer.
The Idaho National Engineering and Environmental Laboratory in the United States has the world’s largest test reactor, the Advanced Test Reactor (ATR), which had continuously used five beryllium neutron reflectors and has started to use its sixth beryllium reflector in 2005.
The application level of beryllium in strategic nuclear energy, advanced fields, and major scientific engineering construction reflects to some extent the comprehensive strength of a country and the level of national defense military technology.

Nanostructured or partially amorphous Al- and Zr-based alloys are attractive candidates for advanced high-strength lightweight materials.
Introduction In recent years, nanostructured materials (single- or multiphase polycrystals with grain or domain sizes in the nanometer range, typically less than 100 nm at least in one dimension) have been attracting much attention due to their scientific and engineering significance [1-3].
Although melt-spun ribbons exhibit an ultimate strength exceeding that of conventional Al alloys by a factor of 2 - 3 [4], their small size prevents engineering applications.
