Ion beam induced spinodal decomposition and amorphization in the immiscible bilayer system UMo/Mg

Preparation of nanoporous molybdenum film by dealloying an immiscible Mo–Zn system for hydrogen evolution reaction

“…It can be seen that Mo atoms diffused a long distance ($600 nm) in Zn layer which is much deeper than the results obtained in other similar work, such as Cu/Fe (25 nm), 18 Cu/Ta (10 nm) 19 and even swi heavy ion irradiated UMo/Mg (110 nm). 20 We speculate the long-distance diffusion of Mo atoms in Zn layer could be attributed to the nanocrystalline structure of Zn layer. Firstly, the average grain size of Zn layer aer annealing is calculated to be 32.6 nm by using Scherrer analysis according to the peak width of (100), ( 101) and (110) of the diffraction pattern shown in Fig.…”

A Phase-Field Study of Spinodal Decomposition Impeded by Irradiation in U-Mo and U-Mo-Zr Alloys

“…The addition of Mo can effectively stabilize the γU-phase and improve the thermal conductivity and anti-swelling property [20], and the addition of Zr can effectively improve the stability of γU-phases over a wider temperature range [14]. It is reported that, with the microstructure of spinodal decomposition, the accumulation of fission gases and the swelling effect could be well detained in U-Mo alloys [21]. In addition, the results of Yao et al's research [7,8] showed that the spinodal decomposition formed nanoscale structures in U-Zr alloys after irradiation, and that this kind of microstructure could effectively prevent the irradiation swelling of fuel slugs.…”
