Research Abstract

Ti-ni alloy is well known as one of the most technologically important shape memory material. Ti and Ni, however, have a tendency to absorb a hydrogen easily. During the study of the effect of hydrogen on Ti-Ni alloy, the shape memory effect (S.M.E.) was found to be induced by hydrogen charging under some conditions. It is considered that this alloy has a possibility to be applicable to a hydrogen sensor. An effort has been focussed on clarifying the relation between S.M.E. and hydrogen charged and found that S.M.E. is dependent upon the amount of hydrogen induced. In applying of this alloy to a hydrogen sensor, however, much attention should be paid to hydrogen embrittlement observed in tensile test. The elongation, in tensile test, was lowered to 0.1 compared with 0.6 of non-charged materials. In glow discharging, which is thought to be mild charging of hydrogen and more similar to actual environment, the evaluation of this ally was also conducted and found that the tensile property was nearly same to the specimens charged electrolytically. This alloy is promising as a hydrogen sensor, although more detailed experiment will be necessary in further study.
