11 Aug 1992TL;DR: An electrochemical hydrogen storage alloy having decreased hydrogen overpressure as well as other desirable operational parameters, comprising on an atomic percent basis: 14 to 22 percent vanadium; 28 to 39 percent nickel; 7 to 15 percent titanium; 15 to 34 percent zirconium; and at least one member selected from the group consisting of 0.26 to 1:0.68.
Abstract: An electrochemical hydrogen storage alloy having decreased hydrogen overpressure as well as other desirable operational parameters, comprising on an atomic percent basis: 14 to 22 percent vanadium; 28 to 39 percent nickel; 7 to 15 percent titanium; 15 to 34 percent zirconium; and at least one member selected from the group consisting of 0.001 to 7 percent chromium, 0.001 to 7 percent cobalt, 0.001 to 7 percent iron, 0.001 to 3.6 percent manganese, and 0.001 to 2.7 percent aluminum, wherein the atomic ratio of the vanadium to zirconium is in the range of 1:2.26 to 1:0.68. An electrochemical hydrogen storage alloy having a reduced self-discharge rate comprising an alloy having a heterogeneous, disordered microstructure resulting from changes in the mutual solubility of the elements of the alloy, wherein hydrogen in a particular phase is not easily discharged either though low surface area, or an oxide of limited porosity or catalytic property.

TL;DR: In this article, the oxide formed on HANA-4 in pure water was observed to have a layered structure with a smaller total oxide thickness for the same corrosion period, a higher layer thickness and a larger columnar grain size in the interface region when compared to Zircaloy-4.

TL;DR: In this article, the hydrogen absorption cracking behavior of Zr-4 has been investigated based on the microstructure, hydrogen absorption amount as well as residual stress, and the results show that the grain size has a pronounced effect on the hydrogen absorbing cracking, with the increase of grain size from 30μm to 500μm, the cracks vary from small cracks of independence to large cracks that connect with each other along the radial direction.
