PHASE TRANSFORMATION IN ZIRCONIUM 10-25% NIOBIUM ALLOYS
Technical Report

OSTI ID:4781208
Zirconium-niobium alloys were studied to develop new matrixes for dispersed plutonium oxide and carbide fuels. Transformation reactions for zirconium base niobium alloys are described. The monotectoid temperature occurs at 597.5 plus or minus 1.5 deg C and the maximum solubility of niobium in zirconium is 2%. Two transformation reactions can occur in alloys containing 10-- 25% niobium. Transformation in the temperature range 450--600 deg C results first in the precipitation of alpha zirconium and finally in the decomposition of the high-temperature BETA phase into the equilibrium forms of alpha zirconium and BETA niobium. Below 400 deg C, a metastable omega phase can occur. In the higher range of temperatures, an increase in niobium content in alloys of this range of compositions results in an increased incubation period and decreased reaction rates for the transformation.
