Elastic moduli of nearly pure polycrystalline plutonium

ORAL

Abstract

We measure elastic moduli of microalloyed poly-crystalline cylindrical specimen of Pu-239. We observe $\alpha \rightarrow \beta \rightarrow \gamma \rightarrow \delta$ phase transitions and find that the elastic moduli of nearly pure plutonium are the same as those of Ga-stabilized plutonium.
