Variation Analysis of Grain Deformation in Aluminum Alloy
Inhomogeneous deformation in polycrystalline material is interesting matter, because the concentration point of deformation relates with the origins of yield, fracture and recrystallization. Plastic strains in three-dimension during tensile deformation have been investigated by using the marker tracking method in synchrotron X-ray microtomography. Three-dimensional position of grains was detected by grain-boundaries visualizing method. The variation of deformation were measured for each grain. We summarized how much degree grains was deformed inhomogeneously comparable to the plastic deformation in whole specimen.
