Improvement of hydriding properties of a Zr1Ni1 alloy by adding third transition metals for tritium recovery

Gaseous phase hydrogen storage and electrochemical properties of Zr8Ni21, Zr7Ni10, Zr9Ni11, and ZrNi metal hydride alloys

“…Therefore, the smaller unit cell of tetragonal Zr 7 Ni 10 in ZN0710A promotes a better reversible storage capacity compared to ZN0710. Comparing ZN0911 and ZN0911A, the reversible storage capacity decreases after annealing due to the increase in secondary ZrNi phase abundance, which has non-reversible hydrogen storage capability [53,68]. The reversible storage capacities for ZN0821/ZN0821A and ZN0101/ZN0101A are comparable.…”

Studies of Ti1.5Zr5.5V0.5(MxNi1−x)9.5 (M=Cr, Mn, Fe, Co, Cu, Al): Part 1. Structural characteristics

“…In AB 5 alloys, the addition of Cu was found to be detrimental to cycle life due to the flattening of the unit cell along the c-axis [32], but improved low temperature specific power by altering the microstructure of the surface oxide and the imbedded metallic clusters within the surface oxide layer [33]. Also, the hydrogen storage characteristic of ZiNi alloy (B33 structure) with partial replacement of nickel by one of the transition metals (V, Cr, Mn, Fe, and Co) was previously studied [34]. In this series of alloys, the equilibrium plateau pressure has a linear dependence on the unit cell volume, and lighter substituting elements (V, Cr, and Mn) have a stronger influence on the microstructure pushing it toward the Laves phases [34].…”

Structure and interstitial deuterium sites ofβ-phase ZrNi deuteride

“…[17][18][19][20] Numerous studies have suggested that the ␣-phase ZrNi metal lattice retains essentially the same structure ͑Cmcm symmetry͒ during hydrogen absorption, forming ␤-phase ZrNiH ͑i.e., monohydride͒ and ␥-phase ZrNiH 3 ͑i.e., trihydride͒. [1][2][3][4]6 The structure and interstitial occupancies of ␥-ZrNiH 3 have been exhaustively studied, 2,6,12 and all the experimental results agree well with the model first proposed by Westlake.…”
