摘要: Abstract The ultimate rolling reduction rate ( r u ) of the as-cast Nb–TiNi alloys was evaluated by measuring thickness changes in cold rolled samples. Furthermore, effects and subsequent anneal on hardness, microstructure, hydrogen permeability Φ flux J Nb 40 Ti 30 Ni alloy (mol%) were examined a Vickers hardness tester, scanning electron microscope (SEM), mass flow meter, respectively. value for reduced with increasing attained to one third original 50% reduction, but recovered at 1373 K 605 ks. Hydrogen varied inversely proportional membrane 673 K. 12 ccH 2 /cm /min sample 120 μm. present work has demonstrated that are effective useful preparation permeation membrane.
