Investigation of plasticity in mg-zn-al based magnesium alloys with graded aluminium content

Popis výsledku v původním jazyce

The objective of this paper has been mapping out of the characteristics of deformation, in particular of plasticity, and determination of medium-sized natural resistance to deformation of Mg-Al-Zn based alloys with graded AI content, specifically AZ91, AZ61 and AZ31. Alloys were also heat treated for the influence of this treatment on characteristic obtaining. The experiment was conducted in a wider interval of forming temperatures, namely 320 - 400 degrees C. Forming temperature of 360 degrees C appeared to be very appropriate for defining the specific values of deformation intensity, at which occurs the beginning of dynamic recrystallisation particularly in the alloys AZ61 and AZ91. Recrystallisation was simultaneously accompanied by re-precipitationof dispersive phase on all the present interfaces. The values of equivalent strain (Se) = 0.13 for AZ61 and, Se = 0.15 for AZ91 appear to be the peak deformations for the onset of dynamic recrystallisation. The applied T4 at the subseque
