A Study of Uranium-fissium Alloys Containing TechnetiumThe presence of technetium did not result in the presence of any new phases; it produced only minor changes in the phase relationships and in the stability of the gamma-uranium solid solution. Studies of aging behavior and of the structure of slowly cooled alloys indicated that the gamma is slightly more sluggish in its transformation characteristics in the presence of technetium. On this basis, it appears that the property measurements made earlier on uranium-fissium alloys which did not contain technetium can be reliably applied to true fissium alloys. |
