This opens a wide field of applications for composite materials and nanomaterials.
These particles may comprise metal or non-metallic materials, organic or inorganic, solid or liquid.
All types of condensed substances, liquids, solutions, polymeric materials, glass, ceramics, ionic compounds and metals or gels may theoretically be used as raw materials in the production of nanofibers (Sodomka, L. 2009).
The use of nanotextiles in the construction and preservation of cultural heritage as carriers of properties to the materials to which they are applied, such as the ability to locally reinforce the damaged historical materials, or to provide resistance to the harmful effects of an aggressive environment, etc., is a promising direction in the development of these materials.

Introduction Magnesium alloy tubes are very attractive metallic structural materials in such applications as bikes and vehicles for handicapped and hospital owing to their low density and excellent damping capability.
Divided flow extrusion is beneficial to improving the productivity and saving materials.
The highest extrusion velocity and rate of metal materials depend on its essential plastic property.
