Studium vlastností vybraných Mg slitin tvářených procesem ECAP

Abstract

Master thesis examines the influence of SPD technologies on the mechanical properties of selected types of magnesium alloys. The theoretical part of the thesis contains a list of the most frequently applied methods based of extreme plastic deformation with goal the obtain good grain refinement of selected alloys with superior mechanical properties. The practical part of the thesis is focused on the realization extrusion process of AZ31 and AZ61 alloy by ECAP process. In the next part of thesis is performed the analyze of influence of input heat treatment T4 on the final structure and mechanical properties. The results obtained of experiments are discussed in final part of thesis.
