| Research Abstract |
The amalgamation of X-Ray diffraction(XRD) microscopy with grain boundary tracking(GBT) produces a novel method for generating accurate analysis of individual grains during deformation(DAGBT). XRD and GBT are both non-destructive techniques which allow for in-situ characterizing of metals in both an un-deformed state and up to close to fracture. Furthermore, during deformation of the specimen, GBT is able to accesses submicron level analysis of the morphology of the grains in 3-dimensions, allowing for detailed analysis of each grain. Using specially developed algorithms, DAGBT generates accurate information about individual grain orientations utilizing near field
