Microstructural Evolution in Partially Homogenized AZ91 Alloy during Hot Rolling and Interpass Annealing

Abstract:

The as-cast AZ91 Mg alloy ingot with mean grain size of 98 μm after solution treatment was subjected to plastic deformation by multi-pass hot rolling. The process facilitated steady grain refinement by dynamic recrystallization with increasing rolling passes, and the final grain size was reduced to 6.4 μm by 4 rolling passes. Optical microscopy demonstrated that in the beginning of the rolling process twin DRX was the major dynamic recrystallization mechanism. In contrast, in 3^rd and 4^th passes of rolling new grains nucleated at grain boundaries, due to low grain size of the alloy.
