Abstract

The cyclic properties of protium storage in Ti-Cr-V alloys with a BCC structure were investigated in order to develop the alloys with good cyclic properties. It was found that the hysteresis factor of pure V was almost unchanged but the hysteresis factor of Ti-Cr-V heat-treated alloys decreased with increasing cycle number. The plateau pressure of Ti-Cr-V heat-treated alloy in absorbing process dropped significantly with increasing cycle number up to the 20th cycle. In contrast to this, there was not any change in PCT curves of pure V metal. This could be originated from the difference in mechanical properties between V metal and Ti-Cr-V alloys.
