Design of Super Heat-Resisting Nb-Based Alloys for Nuclear Applications

Plastic instability behavior of bcc and hcp metals after low temperature neutron irradiation

“…The selection of these metals for analysis was because they are the primary components of alloys used for fission and fusion reactor applications at elevated temperatures [12][13][14][15]. Discussion is focused on the flow curve behavior after irradiation and on the dose dependencies of the PIS and YS.…”

Alloying effects of Ru and W on the resistance to hydrogen embrittlement and hydrogen permeability of niobium

“…In fact, niobium is known as the base metal of the high temperature structural materials for nuclear industry [11]. Also, the solid solution hardening is expected by the addition of ruthenium or tungsten into niobium metal [12]. Therefore, the alloying of Ru or W into niobium is favorable not only for improving the resistance to hydrogen embrittlement by reducing hydrogen concentration, but also for strengthening the mechanical properties at high temperatures, which will lead to the long-term durability of the hydrogen permeable membrane.…”
