Microstructural development and radiation hardening of neutron irradiated Mo–Re alloys

Microstructural and mechanical property changes with aging of Mo–41Re and Mo–47.5Re alloys

“…Furthermore, no streaking or super-lattice reflections were observed in the diffraction patterns to suggest any decomposition or ordering of the solid solution phase. The single-phase solid solution structures observed in the as-annealed and aged samples correlates with work by Nemoto et al [22] on Mo-Re alloys, in which no evidence of precipitation of secondary phases were observed in Mo-41Re aged for 720 h at temperatures up to 1073 K by either TEM or X-ray diffraction techniques.…”

Aging effects on microstructural and mechanical properties of select refractory metal alloys for space-reactor applications

“…Images of the 1098 K aged Mo-41Re taken from OM and TEM are shown in Fig. 4, with a representative selected area [13] on Mo-Re alloys, also observed no evidence of precipitation in Mo-41Re aged for 720 h at temperatures up to 1073 K. The sluggish kinetics at these temperatures suggests some degree of stability, though enhanced precipitate formation may occur under radiation environments. Differences were not observed in the tensile properties of Mo-41Re between the as-annealed and the 1098 and 1248 K aged materials (Table 5).…”

A Review of Dangerous Dust in Fusion Reactors: from Its Creation to Its Resuspension in Case of LOCA and LOVA

“…The anisotropic microstructure of W allow its use for fabrication of pipes and plates [61]. "So far, only rhenium is known to improve the ductility of tungsten by solid solution but its use for fusion energy applications has been ruled out for reasons of cost and irradiation embrittlement.…”
