Axil, unless there is some limit on loading your talking about, both Nickel and titanium will "load" hydrogen/deuterium into their lattice. Titanium was what Steve Jones first used in his first CF experiments because it would load more deuterium than palladium greater than one I believe. . Nickel doesn't load deuterium at all though, but would load hydrogen up to 0.8 H/Ni. Correct me if I'm wrong. Anyway nitinol does load hydrogen just a little too well. What ever causes nitinol's shape metal properties disappears has hydrogen concentrates in the lattice.
