Evaluation of corrosion resistance of magnesium alloy AZ61
Hlavnička, Jiří ; Horynová, Miroslava (referee) ; Doležal, Pavel (advisor)
This work is foccused on assessment of corrosion resistivity and character of corrosion attack of AZ61 magnesium alloy. Squeeze casting specimens in both as-cast state and in solution annealing state were used as the experimental material. Corrosion degradation was performed in a salt spray fog (5% solution of sodium chloride). Mechanism of corrosion, appearance and depth of corrosion attack have been evaluated.

Fatigue properties of magnesium alloy AZ31 after corrosion degradation
Horynová, Miroslava ; Lukáč, Pavel (referee) ; Doležal, Pavel (advisor)
The present study is focussed on assessment of cyclic deformation response and fatigue behaviour of bare and precorroded AZ31 magnesium alloys. Corrosion degradation was carried out in a salt spray fog (5% solution of sodium chloride) for 480 and 1000 hrs. Microstructure, mechanical properties, low- and high-cycle fatigue behaviour of experimental material in as-cast condition has been evaluated. Furthermore, the corrosion behaviour of material has been investigated. The fatigue tests have been performed using precorroded specimens to assess influence of corrosion degradation on cyclic deformation response and on low- and high-cycle fatigue behaviour. Influence of local corrosion degradation on initiation of fatigue cracks has been studied.
