Alloys of Uranium With Zirconium, Chromium, Columbium Vanadium, and Molybdenum

“…The p a t t e r n obtained (35) The solubility of molybdenum in beta u r a n i u m is a maximum of 1.0 p e r cent a t the eutectoid t e m p e r a t u r e .

“…X-ray diffraction patterns of the pellets showed the presence of a single phase fluorite structure. 54 The various compositions of uranium oxide were prepared in two ways. The three pellets were placed one upon the other and clamped between two Vycor rods.…”

Phase studies in the uranium-hafnium system

“…Of these, titanium (21), zirconium (22,24), columbium (25) , and plutonium (22) are soluble in all proportions. Ilolybdenum (26,27,28), vanadium (29) and chromium (30) are soluble to the extent of 40, 12 and 4 atom ic percent respectively. Tantalum (31) which usually shows marked similarity to columbium in its chemical and metallurgi cal properties is soluble to only a very limited extent.…”
