Solubility of hydrogen in V-4Cr-4Ti and lithium
- Argonne National Laboratory, Chicago, IL (United States); and others
The solubility of hydrogen in V-4Cr-4Ti and liquid lithium was determined at 400-675{degrees}C and a hydrogen pressure of 1.76x10{sup -4} torr (2.35 x 10{sup -2}Pa). Hydrogen concentration in both materials decreased as temperature increased, and the ratio of the hydrogen concentration in liquid lithium and V-4Cr-4Ti (hydrogen distribution ratio R) increased with temperature, e.g., R was {approx} 17 at 400{degrees}C and {approx} 80 at 700{degrees}C. Desorption of hydrogen from V-4Cr-4Ti is a thermally activated process and the activation energy of the desorption rate is 0.405 eV.
