Microstructural characterization by combined EBSD and X-ray diffraction analysisis shown for an FCC material deformed by rolling and further heat treatment on air.The wide variety of x-rays sources combined with EBSD allows some correlationsbetween microstructural parameters tobe withdrawn by carefully analyzing x-raypeak broadening. The combination of both techniques provides a deeper understandingof anisotropic accumulation of dislocation arrays on a deformed F 138 stainlesssteel. The anisotropy results in a smaller peak breadth for crystal orientations with[110] planes contained on the rolling plane, further explained as resulting from a lowerstorage of dislocations. After heat treatment the effect is reverted and the formerly lessmisoriented orientations become more uniformlyoriented revealing a faster dislocationmigration and annihilation and/or trapping
