It is common to speak about multi-scale material, meaning that the properties and the behaviors of the material are predetermined for different length scales ranging from nanometers to meters. In materials science, this approach enables researchers and engineers to enhance performance since the properties in each tier are different.

Usually at the nanoscale, inhibitor of materials, some characteristics such as strength electrical conductivity, and optical features of the material will be improved. For instance, select nanomaterials have greater hardness than their bulk and this allows for the design of parts that are lighter yet stronger than traditional parts. When passing from the nanoscale to the micro and then to the macro scale, the material’s microstructure has a dominant effect on overall performance.

Grain size, distribution of phases, and the type of defects are instrumental in determining many macroscopic properties of a material. Specific knowledge of how these microstructural features affect overall material properties is essential for use in a wide variety of industries such as aerospace, automobile, and biomechanics. For instance, the endurance of a part can be improved by microstructural control by the use of alloying, heat treatment, or mechanical processing.

Moreover, multi-scale materials can also use hierarchical structures in which properties of different scales of materials can be realized cooperatively. For instance, it is now possible to design reinforcement fibers at micro-scale levels with a polymer matrix at macro-scale levels in order to increase mechanical properties as well as to decrease the identified weight.

Multi-scale material design and characterization are challenging, and methods such as electron microscopy, X-ray diffraction, and modeling are applied. By utilizing multiscale mechanics data, investigators can better anticipate material action and design properties for certain functions.

In conclusion, it could be noted that multi-scale materials are one of the fresh tendencies in materials science, allowing to creation of new unique materials and materials products with improved performance and multifunctionality for numerous application areas. The kind of design of these materials and even their optimization makes them ready to face the ascription of today’s engineering and technology.
