Description: The mechanical behavior of uranium and its alloys is reviewed with special emphasis on plastic flow behavior of polycrystalline materials. The strength of uranium is influenced by crystal structure as well as by point, planar, and volume defects; wit these factors in mind, texture hardening, strain hardening, solute hardening, grain and subgrain size hardening, and precipitation and particle hardening are discussed. Temperature and strain rate influence the various strengthening mechanisms in different ways, and these variables are considered whenever possible. Unusual mechanical effects result from the polymorphic nature of uranium and from anisotropic properties of alpha uranium such as thermal expansion and elastic stiffness; their importance on plastic flow is considered. Uranium and its alloys can be made superplastic, and the factors which contribute to such characteristics are discussed. (101 references) (auth)
