Microstructure and mechanical properties of ultrafine-grained magnesium AZ91 alloy
Original language description
Microstructure, mechanical properties, cyclic plastic deformation behavior and fatigue strength of ultrafine-grained (UFG) magnesium alloy AZ91 processed by equal channel angular pressing (ECAP) were investigated. ECAP of originally cast alloy results indevelopment of bimodal structure, improved yield stress, tensile strength and ductility when compared to the as-cast state. Endurance limit based on 107 cycles is also improved, however exhibits large scatter. Initiation of fatigue cracks takes place inregions of large grains in the bimodal structure, where the content of Mg17Al12 particles is low.
