Research Abstract |
The alloying effects on the mechanical property, the hydriding property and the hydrogen permeability of Nb-W alloy membrane are investigated to propose the concept for alloy design to improve the durability. From the experimental results, it is clear that the amount of hydrogen solubility for niobium decrease with adding the molybdenum. The softening temperature of niobium based alloy is increased by adding the tungsten. The excellent heat resistance, high workability and high hydrogen permeability can be obtained by adding tungsten with molybdenum into niobium. On the other hand, the durability of Nb membrane can be improved by forming the oxide layer between Pd catalytic layer and Nb, because the oxide layer block the diffusion reaction between them.
