Microprocesses of plastic deformation in light metals based advanced alloys and composites at elevated temperatures

Anotace

Advanced materials are very important for industries from economic as well as ecological point of view. Light materials based on aluminium and magnesium alloys and composites become of special importance in many applications, especially in the automotive industry. Application of such materials is limited because of rapid decrease of mechanical properties at higher temperatures. Detail knowledge of high temperature deformation mechanisms is crucial problem for useful applications or further development of these materials with enhanced properties. From a conventional mechanical testing, parameters are frequently obtained that cannot be easy interpreted and cannot be used for a determination of processes governing the resistance of materials under consideration against straining. According to authors of present proposal, deeper understanding of strain phenomena in light metals based alloys and composites necessitates a concentrated approach in their investigations based on the application of various conventional as well as non-conventional techniques that reflects responses of these materials to various manners of straining. Complex analyses of these responses and their mutual relations could only lead to the explanation - at least some - factors including parameters of structure determining the strain behaviour of materials under consideration. The present project is aimed to such complex analysis.
