Uranium Alloys for High-Temperature Application

Thermo-physical properties of DU–10wt.% Mo alloys

“…In general, average instantaneous coefficients of linear thermal expansion for the DU-10Mo alloy obtained in the current work are slightly higher than those obtained for similar alloys in published literature. Values obtained for the DU-10Mo alloy upon heating are very similar to those presented by Saller et al up to the temperature range 300-1073 K [18]. Values upon cooling are very similar to the only other available data on a U-10 wt.% Mo alloy [19].…”

Effect of Si and Zr on the interdiffusion of U–Mo alloy and Al

“…This means that the c-phase U-7Mo decomposes at this temperature so fast that a Zr addition does not influence the initial stage of the decomposition. It is known that U-Mo alloy has a greater degree of thermal stability than U-Zr [13], and the effect of a Zr addition on the c-phase U-Mo is to decrease the c-phase stability of U-Mo alloys [14,15]. This was observed for a longer annealing test as shown in Fig.…”

Thermomechanical process optimization of U-10 wt% Mo – Part 1: high-temperature compressive properties and microstructure

“…For this, an alloy that offers a good combination of irradiation performance, oxidation resistance, strength, and ductility is required for test-reactor applications. Various uranium alloys have been evaluated for many decades looking at mechanical properties and susceptibility to oxidation and corrosion [3][4][5][6].…”

“…There is very limited mechanical data available in the literature for U-10Mo alloy for the expected process conditions (temperatures and strain rates). Generally, that which is available, such as Saller [6] and McGeary [5], is not in a relevant composition or processing condition, making precise predictions difficult. Although several studies have evaluated the properties of uranium alloys, none have looked specifically at the strain-rate sensitivity of U-10Mo [2,3,6,7,[9][10][11][12].…”
