Effect of grain shape and texture on the earings in an Al-Li alloy

The effect of crystallographic texture, grain size and shape on the earing in an Al-Li alloy system was examined. The textures were shown to have more effect on the earings. While the effect of grain size was small in the specimens of equiaxed grains, the effect of grain shape was very large. It was found that the deformation level changes the effect of grain shape on the deformation anisotropy. When the deformation level is low, the effect of grain shape on deformation anisotropy is large because dislocation networks are developed near grain boundaries.
