Outline of Final Research Achievements

The effect of alloying elements on the strengthening was studied in some magnesium alloys processed with plastic deformation. The mechanism of deformation-induced strengthening in such alloys were also studied. The alloying elements affect the strength of deformed specimens, although they do not alternate the microstructure after plastic deformation, such as reduction of grain sizes or segregation to grain boundaries. The results implies that alloying elements affect the reaction between dislocations and grain boundaries and alternate the strength after deformation process.
