Abstract

The present study aims to investigate the effects of addition of Mn to Ti-Cr-V alloys on their protium absorption properties and to find the design criteria for increasing effective protium capacity. The effects of V and Mn content of the alloys on the protium absorption properties of heat-treated Ti-Cr-V-Mn alloys in low pressure regions were studied at various temperatures, and it was found that increasing Mn content and decreasing V content unstabilize protoride in low pressure region. The PCT curves from low pressure plateau region (10-1 -105 Pa) to high pressure plateau region (105-107 Pa) shifted to the side of low protium concentration. It was found that the addition of Mn or decreasing V content in the alloys is effective for increasing effective protium capacity.
