Development of shear bands during deformation of partially solid alloys
Résumé
The development of shear bands in partially solid alloys is investigated during the deformation of a magnesium alloy at similar to 45% solid during equiaxed solidification. Results show that shear bands initiate after reaching the peak stress and then increase in thickness during strain softening from similar to 10 to similar to 16 mean grains thick. Once shear bands become fully developed, shear continues at approximately constant stress and volume.
