Inhomogeneity of texture, particle precipitation and grain size under recrystallization of Al-Mg, Al-Mg-Li and Ai-Mg-Sc alloys
The X-ray rocking curve method (RCM) was used to characterize microstructure and texture of Al and alloys: Al-Mg (AMg6) and Al-Mg-Li (1420), Al- Mg-Sc (1570) after cold rolling to a 8-70% reduction in thickness, and then annealing at 300-550degreesC. The fractions of recrystallized grains with {111}, {100}, {113} and {110} orientation in the sheet plane and its distribution on the sizes was measured by a RCM. For these alloys a grains with orientation of {111} and {100} grow much faster than grains {113} and particularly {110}. In an alloy 1420 at 300-400degreesC continuous recrystallization takes place with fine grains and weakening rolling texture
