摘要：
The cyclic properties of hydrogen absorption and desorption in V55Ti20.5Cr18.1Fe6.4 alloy were studied. With increasing of cyclic number, the hydrogen content drops and the decay rate of hydrogen desorption content slows down. The hydrogen desorption plateau region becomes narrowed and the hydrogen desorption pressure increases with increasing of cyclic number. Some compounds deteriorating the alloy property appear on the alloy surface and the alloy shows double phase structure of bcc and fcc after cycles. The alloy grains have been pulverized gradually due to the accumulation of cracks introduced during the absorption-desorption cycles.
