Abstract

Small dogbone SS-Teeny tensile samples fabricated from Zry4 baseplate and UAM were tested in uniaxial tension while WAXS synchrotron data was collected along the gauge length and at multiple rotation angles. This allowed for the comparison of dislocations, strain, and texture throughout the deformation process. The UAM process resulted in a more homogenous starting texture than the baseplate, however similar final textures were observed after deformation. This necessitated different slip systems to be activated in the UAM samples to converge on a similar final texture. The observed changes in texture mirrored the changes in the relative fractions of different dislocation types based on the dislocation burgers vectors. Future work will characterize how this impacts deformation at elevated temperatures.
