Study of Uranium-Plutonium Alloys Containing from 0 to 20% of Plutonium); ETUDE DES ALLIAGES URANIUM-PLUTONIUM AUX CONCENTRATIONS COMPRISES ENTRE 0 ET 20% DE PLUTONIUM
Thesis submitted to Universite, Paris. The work is carried out on U--Pu alloys in the region of the solid solution uranium alpha and in the two-phase region uranium alpha + zeta phase. The results obtained concern mainly the influence of the addition of plutonium on the physical properties of the uranium (changes in the crystalline parameters, the density, the hardness) in the region of solid solution uranium alpha. In view of the discrepancies between various published results as far as the equilibrium diagram for the system U-- Pu is concerned, an attempt was made to verify the extent of the different regions of the phase diagram, in particular the two-phase region. Examinations carried out on samples after various thermal treatments (in particular quenching from the epsilon phase and prolonged annealings, as well as a slow cooling from the epsHon phase) confirm the results obtained at Los Alamos and Harwell.
