Effect of neutron irradiation on low temperature toughness of TiC-dispersed molybdenum alloys

Development of Nanostructured Tungsten Based Materials Resistant to Recrystallization and/or Radiation Induced Embrittlement

“…Accumulation of radiation induced defects can be suppressed by introducing a high density of sinks, such as grain boundaries and dispersoids, for the defects. Our preceding study on nanostructured Mo showed an encouraging result: 9,10) Structural changes occurring under un-equilibrium states of radiation environments lead to significant increase in ductility compared with that in the unirradiated states. This phenomenon is opposite to radiation embrittlement and regarded as radiation induced ductilization (RIDU).…”

High temperature strength of fine-grained, particle-dispersed V–(1.7–2.4)wt%Y alloys with different grain sizes and particle densities

“…The resistance to radiation embrittlement in refractory metals was shown to be improved by introducing microstructures of fine grains and finely dispersed particles [6][7][8][9][10]. For vanadium the authors proposed a powder-metallurgical process to reduce grain size associated with finely dispersed particles and ensure good ductility of vanadium by removing solute oxygen and nitrogen from the matrix [11].…”

Development of ultra-fine grained W–TiC and their mechanical properties for fusion applications

“…This indicates the significance of further grain refinement for ductility enhancement. In addition, recent experimental and simulation studies of radiation effects on fine/refined/nanocrystalline materials [7][8][9][10][11][12][13][14][15][16][17][18][19] showed that these structures are effective in improving radiation resistance. However, there have been no reports on the effect of grain refinement on radiation resistance for W and its alloys.…”
