- Resumen es exacto "Microstructure of alloys for technological use depend of chemical composition and the solidification rate achieved during its elaboration. Hence hypothesis that will frame the present research can be summarized in that the refinement of the microstructure give it certain mechanical and surfaces properties different to those of their peers obtained by conventional solidification process. In order to this, general objective of present research is study microstructural features of light alloys series of technological interest. Alloys obtained through different unconventional solidification techniques and determine their possible application as a surface material. Development of light alloys, mainly nanostructured Aluminum alloys, with high mechanical resistance and good behavior against corrosion is of great importance in the field of structural materials. Rapid Solidification techniques, such as Melt Spinning, allow obtaining a wide variety of "Nanostructured Alloys", whose characteristics could significantly improve their mechanical behavior. Likewise, the application of rapid solidification surface techniques, for example Thermal Spray process, promotes the generation of coatings containing phases with particular characteristics such as quasicrystalline ones that improve their aptitudes as surface materials. This research work contributes to the development of new alloys with high specific mechanical resistance for structural applications and tribological interest in different industries. On the other hand, it`s a great contributions to the knowledge in the field of materials science."
