Book Description
The high-temperature body-centered cubic gamma phase in uranium alloys with approximately 10 at.% titanium, niobium, zirconium, or molybdenum can be rendered metastable under critical cooling conditions; it may transform thence by a shear mechanism to form a characteristic banded structure or by a nucleation and growth process to equiaxed grains. These decomposition structures with differing metallographic appearances give similar x-ray patterns. The structures are designated "distorted alpha " since the patterns correspond to a contraction in the b-direction of the normal ortho rhombic alpha cell. The formation of these metastable structures is apparently dependent upon composition, cooling rate, and the effect of the solute element on the incubation period and decomposition rate of the metastable gamma phase. (auth).

Book Description
The high-temperature body-centered cubic [gamma] phase in uranium alloys with approximately 10 at % titanium, niobium, zirconium, or molybdenum can be rendered metastable under critical cooling conditions; it may transform thence by a shear mechanism to form a characteristic banded structure or by a nucleation and growth process to equiaxed grains. These decomposition structures with differing metallographic appearances give similar x-ray patterns. The structures are designated ''distorted [alpha] '' since the patterns correspond to a contraction in the b-direction of the normal orthorhombic [alpha] cell. The formation of these metastable structures is apparently dependent upon composition, cooling rate, and the effect of the solute element on the incubation period and decomposition rate of the metastable [gamma] phase.
