The changes in density and hardness as a result of annealing at temperatures up to 600 deg C are reported for and aluminum-clad Al-5 wt% Ra andd Al-10 wt% Pu alloy in which 89.3% andd 75.6%, respectively, of the plutonium atoms were fissioned. The density of the irradiated specimens at room temperature decreased after pulse anneals of 15-min duration at temperatures above 525 deg C, whereas for lower andnealing temperatures the density of the specimens increased. The hardness of the specimens at room temperature decreased substantially after annealing at temperatures between 275 deg C andd 360 deg C. A specimen of 1100 aluminum which was heavily deformed by rolling was also annealed in a manner similar to the irradiated materials. The density of the aluminum at room temperature increased after pulse anneals at temperatures up to 600 deg C, and the hardness decreased after annealing at temperatures above 300 deg C. (auth
