Effect of aluminium and calcium on the microstructure, texture, plastic deformation and related acoustic emission of extruded magnesium-manganese alloys
Original language description
Alloying modifications with Ca and Al of a binary Mg-1 wt.% Mn have been used to investigate the microstructure development during extrusion and the relation between these microstructures and the mechanical properties. Acoustic emission (AE) measurementswere used to analyse dislocation or twin dominated deformation in differently textured fractions of the microstructure during tensile and compression testing. Ca appears to have a texture modifying effect and leads to the formation of unusual texture components with a tilt of basal planes out of the extrusion direction. This texture development has previously been described for rare earth containing magnesium alloys after extrusion. Al as an alloying element does not lead to the formation of such a component. Both elements have in common, that the alignment of basal plane normals perpendicular to the extrusion direction is reduced, having a substantial effect on the mechanical properties. Partially recrystallised microstructures obtain
