Mechanism of Superplastic Deformation in AlMg Alloy Containing Scandium AITranslate
Abstract AITranslate
Microstructure and dislocation behavior of the aluminium magnesium alloy containing scandium in the process of superplastic deformation were investigated by transmission electron microscope.The results show that four processes will take place in sequence during superplastic deformation, i.e., dynamic recrystallization;dislocations come from grain boundaries;motion of the dislocations within the grains is prohibited by the secondary phase Al3Sc as well as dislocations climb up and go over the dispersed particles;dislocations are annihilated in grain boundaries.It is found that dynamic recrystallization is the microstructure effect of the alloy and play a role in inducing microfine grain superplasticity during superplastic deformation. The dominant mechanism of superplastic deformation is that grain boundary sliding process will be accompanied by intergrainular dislocations.
