Statistical Thermodynamic Analysis for Hydrogen Absorption Behaviour in a Four Monolayers (4 ML) Thick <i>bcc</i> Vanadium (110) Superlattice Being in Contact with Molybdenum Layer

“…1) In the earlier statistical thermodynamic analyses for solution of interstitial element X into the substitutional alloy lattice A 1¹y B y , suppressed solubility of X in the alloy A 1¹y B y compared with that in the metal lattice A was represented by the decreased ª in the A 1¹y B y compared with that in the pure metal A 3,4,9,10,20) and, on the contrary, the enhanced solubility of X in the alloy A 1¹y B y compared with that in the metal lattice A was represented by the increased ª in the A 1¹y B y compared with that in the pure metal A. 9,14,15,19) According to available information, 3,4,20) alloying with the VIa-group elements such as Mo and W into lattice of Vagroup metals like V, Nb and Ta would lead to decrease of ª for H solubility in the alloy phase. For example, ª for bcc Nb 1¹y Mo y H x lattice was determined to be 0.75 for y = 0, 0.45 for y = 0.1, 0.30 for y = 0.2 and 0.20 for y = 0.3.…”
