Hydrogen sorption by the metallic glass Ni64Zr36 and by related crystalline compounds

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

“…Among the annealed alloys, only DH (heat of i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 7 ( 2 0 1 2 ) 1 6 0 4 2 e1 6 0 5 5 hydride formation) and DS of ZN0710A can be obtained (À46 kJ mol À1 H 2 and À130 J K À1 mol À1 H 2 , respectively). These results are very similar to the previously reported values for annealed Zr 7 Ni 10 (À50 to À47 kJ mol À1 H 2 and À144 to À132 J K À1 mol À1 H 2 [39,40,44,48,69], respectively).…”

Thermodynamic Modeling of the Undercooled Liquid in the Ni–Zr System

“…The mixing enthalpies in the liquid have been studied at 1565 K, 19) 1784 K, 22) 1838 K, 22) 1916 K, 23) 1963 K, 24) and 2270 K. 23) At low temperatures, the formation enthalpy of amorphous alloys was measured by Turchanin et al, 25) Spit et al 26) and Henaf et al 27) where there measurements are not in agreement. The formation enthalpy reported by Truchanin et al 25) is a more negative result and in this case the amorphous phase would be more stable than the intermetallic compounds.…”

Thermodynamic Analysis of the Phase Equilibria in the Nb-Ni-Zr System

“…In this binary system, the phase boundaries have been investigated over the entire composition range by Kirkpatrick and Larsen,32) and for the Ni-rich region by Bsenko 33) 35,36) and the enthalpy of formation for the compound phases [37][38][39][40] have been reported. A critical assessment of this binary system has been carried out by Nash and Jayanth, 41) and a thermodynamic assessment has been reported by Saunders. 42) Ghosh 43) has performed a thermodynamic reassessment of this binary system, taking into account the formation of Ni 3 Zr and Ni 11 Zr 9 , and the homogeneity range of Ni 5 Zr and Ni 10 Zr 7 , which were excluded by Saunders.…”
