Influence of Deformation on Precipitation and Recrystallization in an AZ80 Magnesium Alloy

Abstract:

Article Preview

Cellular precipitation is reduced greatly by deformation at all ageing temperatures. Precipitates within twins are often nodular and sluggish to grow, whereas dislocations created by basal slip in matrices promote fast growth of plate-like precipitates. Recrystallization was observed concurrent with precipitation above 310°C. Effective nucleation sites for recrystallization are positions connecting twins and grain boundaries or the intersections of twin variants.
