Abstract
Metallic alloys with microstructures containing amorphous, metastable and nano-structured phases represent a new class of materials with surprising properties, which result both from intrinsic characteristics of the structure and from the presence and combination of phases produced by the compositions and by the different types of non-equilibrium processing techniques. In this context, the objective of this project is the development of technologies appropriate for the processing of amorphous, metastable and nanostructured metallic alloys with the following four specific objectives: 1) production, forming and welding of components with glassy and nanocrystalline metals of Cu, Ni, Ti, Zr or Al based alloys aiming the technological use of the high mechanical strength associated with the metastable structure; 2) recycling of high strength aluminum alloys aiming, through rapid solidification and / or severe plastic deformation, to produce microstructures with characteristics that allow their reuse in noble applications; 3) coatings of steel components with amorphous, nanocrystalline and /or quasicrystalline Fe based, Cu based and Al based alloys aiming to improve corrosion and wear properties; 4) development of nanostructured Mg-based composites with good hydrogen sorption properties for use in hydrogen storage systems.
