Description This study involved fabrication of simulated plate fuel elements. Uranium silicide of actual fuel elements was replaced with yttria. The fabrication stages were otherwise identical. The final cold rolled and/or straightened plates, without stress relief, showed an inverse relationship between bond strength and out of plane residual shear stress (tau(13)). Stress relief of tau(13) was conducted over a range of temperatures/times (200-500 degrees C and 15-240 min) and led to corresponding improvements in bond strength. Fastest tau(13) relief was obtained through 300 degrees C annealing. Elimination of microscopic shear bands, through recovery and partial recrystallization, was clearly the most effective mechanism of relieving tau(13). (C) 2014 Elsevier B.V. All rights reserved.
