对Ti 0.31 Cr 0.49 V 0.20 bcc合金进行了氢和氘压力-成分（PC）等温线测量。结果，残余氢-金属比（H/M）res与残余氘-金属比（D/M）res几乎相同;（H/M）res和（D/M）res约为0.5。此外，中子散射实验进行与Ti 0.31 Cr 0.49 V 0.20合金，包括残留的氢和/或氘。结果表明，当H/M= 0.5时，在第一次吸氢循环中吸附的H原子在脱附循环中几乎不以残氢的形式结合，而当部分使用D2气体时，D原子主要以残氘的形式结合在Ti 0.31Cr0.49V0.2 0 bcc合金中.
Hydrogen and deuterium pressure-composition (PC) isotherm measurements were carried out for Ti 0.31 Cr 0.49 V 0.20 bcc alloy. As a result, the residual hydrogen-to-metal ratio (H/M) res was almost the same as the residual deuterium-to-metal one (D/M) res; the (H/M) res and (D/M) res were approximately 0.5. Furthermore, the neutron scattering experiments were conducted with Ti 0.31 Cr 0.49 V 0.20 alloys including the residual hydrogen and/or deuterium. It was found that H atoms absorbed in the first absorption cycle up to H/M= 0.5 are hardly bound in the desorption cycle as the residual hydrogen, whereas D atoms are mainly bound in Ti 0.31 Cr 0.49 V 0.20 bcc alloy as the residual deuterium when D 2 gas is partially used in the H absorption reaction.
