Influence of Heat Treatment on Irradiation-Induced Dimensional Changes in Some Uranium-Zirconium Alloys


Specimens made of alloys containing 1, 2, and 3 weight percentage of zirconium in uranium were irradiated under conditions where the specimens were free from physical restraint. The specimens studied were from cast, wrought, and wrought and heat-treated materials. The heat treatments investigated included quenching from the gamma phase, quenching and tempering, isothermal transformations, and alpha phase annealing. All specimens were found to increase in length as a result of irradiation except a rolled and alpha-annealed group, which was observed to shorten. The rate of change of length with uranium atom burnup was found to depend strongly upon the prior metallurgical history of the specimens and upon their compositions.
