Vliv extrémní plastické deformace na strukturu a vlastnosti hliníku a slitiny hliníku

Abstract

Due to its properties is aluminum and its alloys are used in all areas of human activity. Materials processed SPD methods are characterized by Ultra-fine grain structure and higher mechanical properties. The main aim of this thesis is to analyze the influence of severe plastic deformation on the structure and properties of aluminum and aluminum alloys by ECAP. The theoretical part contains information and uses of aluminum and its alloys. In the experimental part of the thesis was aluminum and aluminum alloys processed by ECAP and was determined the change in hardness, grain size and structure development during forming.
