Wide application scope, large size and too much consumable are features of building shielding materials, which is different from shielding materials used in electronic industry, so cost reduction is needed.
Materials and Methods Materials.
As metallic materials, amorphous alloy have high conductivity.

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.

Simultaneously, the service behavior of the bamboo/steel slabs is pecfect and there is execllent composite effect between the two different materials.
And the strain is basically the same at the interface of the two kinds of materials.
Bamboo/steel composite beam composites with two different plate materials by structural adhesive.
Because the thickness of composite beam's flange plate is large relatively, the strain gradient changes intersection between surfaces of two different materials.
