- V added to the alloy has substantially the same molecular weight as Ti and Cr, so that even if the amount added is large, the hydrogen storage capacity per unit weight of the obtained alloy does not significantly decrease. However, they are very expensive, especially those with high purity (99.99%) used in these alloys, and are extremely expensive. There was a problem that the cost of the alloy for storing hydrogen would increase.

It is another object of the present invention to provide a hydrogen storage alloy which can obtain an alloy having the BCC type as a main phase, and is excellent in cost and hydrogen storage amount per unit weight and has high practicality. Disclosure of the invention
- a hydrogen storage alloy of the present invention is a hydrogen storage alloy having a body-centered cubic structural phase capable of storing and releasing hydrogen as a main phase, and having a composition represented by a general formula T i ( 100 _ a _ 0. 4b) C r (a _ .. 6b) is represented by a composition formula of M b, wherein M also has a no less of M o element or W element is one element and 2 0 ⁇ a (at%) ⁇ 80, 0 ⁇ b (at%) ⁇ 5.

- the value By setting the value to less than or equal to 0, it is possible to minimize or eliminate the decrease in the hydrogen storage capacity per unit weight due to the increase in the weight of the obtained alloy, and it is expensive in these alloys. Since it does not contain significant V, it is possible to obtain a hydrogen storage alloy at low cost.
- the addition of other elements within a range that does not significantly affect the properties of the hydrogen storage alloy is optional.

- FIG. 2 shows a T i -C r binary system phase diagram related to the present invention.
- the BCC type phase exists in the entire composition range in the Ti-Cr system. Since the atomic radius of Ti (0.147 nm) is larger than the atomic radius of Cr (0.130 nm), increasing the Ti content in the alloy and decreasing the Cr content will increase the lattice constant of the BCC type phase. And the plateau pressure drops.
- the plateau pressure of the hydrogen-absorbing alloy changes depending on the operating temperature of the alloy.However, it is sufficient to select the Ti / Cr ratio appropriate for the target operating temperature by changing the ratio of Ti to Cr.
- T i 40 C r 6 as in the embodiment has a suitable plug bets one pressure the starting composition in 40 ° C (313K).
- the present invention is not limited to this, and the plateau pressure of these hydrogen storage alloys varies with the operating temperature of the alloy.
- the plateau pressure of the alloy can be controlled by changing the ratio of the claw and the Cr content a is 80 at ° / . When the pressure exceeds, the plateau pressure rises remarkably, and conversely, 20at ° /. If it is less than 1, the plateau pressure becomes extremely low and practicality becomes poor.Therefore, it is only necessary to select an appropriate Ti / Cr ratio for the target operating temperature in the range of 20 ⁇ a (at%) ⁇ 80. .
- the Mo element or the W element also has a strong BCC type forming ability with respect to the Ti-Cr binary alloy as described above, and the Mo element or the W element
- the addition of the element is effective because it facilitates the formation of the BCC type
- the Mo element or the W element is a heavy element having a relatively large atomic weight. Addition increases the specific gravity of the resulting water-absorbing alloy, and as shown in Fig. 9 and Fig. 10, when its content exceeds about 5 at%, the maximum occlusion characteristics decrease significantly. I will invite you. Therefore, the basic formula T i (100 _ a _ 0.4 b) C r ( a — Q.

- This error Beth phase is represented by a set configuration of type 2 AB, ideal to take the geometric structure, A, atomic radius ratio of B both atoms in these compositions (rA: rB) Should be approximately 1.225: 1
- the atomic radius of Cr is 1.13: 1, which deviates from the ideal value described above, and is not suitable for forming an ideal Laves phase structure.
- the increase in the amount of Ti means that the Ti site has apparently invaded the B site more, and as a result, the atomic radius ratio between the A site and the B site has decreased. This is thought to be due to the inhibition of the Laves phase formation.

(Approximately 4 to 5 times) was repeatedly and carefully carried out to improve the homogeneity, and the homogenized ingot was kept in a temperature region immediately below its melting point for a predetermined time to perform a heat treatment.
- the heat treatment temperature of these heat treatments is such that a BCC type temperature region exists immediately below the melting temperature of the alloy having the composition to be obtained.
- the treatment may be carried out in a temperature range just below the melting temperature, for example, the above-mentioned Cr element is about 60 at ° /.
- the composition containing it is sufficient to carry out the heat treatment while maintaining the temperature at about 1400 ° C, but it is intended to obtain the temperature of these heat treatments.
- Based on the composition of the alloy it may be appropriately selected from a temperature range immediately below the melting temperature at which the alloy becomes a BCC type.
- the heat treatment temperature may be selected in consideration of these viewpoints.
- the time for performing these heat treatments is too short, the formation of a sufficient BCC-type structural phase cannot be obtained, and if the time is too long, not only does the heat treatment cost rise, but also the heterogeneous phase precipitates and the hydrogen storage properties are increased.
- it may be appropriately selected based on the temperature of the heat treatment, but is preferably in the range of 1 minute to 1 hour.
- the heat treatment is performed as it is after the ingot is melted without forming the alloy, so that it is not necessary to heat the cooled alloy again, and it is efficient.
- the present invention is not limited to this, since it is possible to obtain an alloy having a BCC type structural phase, but the present invention is not limited to this.
- a strip casting method, a one-sided one-piece method, an atomizing method Once formed into a plate, ribbon, or powder by a method such as that described above, these are once cooled and the above-mentioned heat treatment is performed on the BCC phase + Laves phase or an alloy containing only the Laves phase to perform the BCC type structure.

From the X-ray diffraction diagram shown in Fig. 3, it can be seen that the Mo element is almost a BCC-type single phase despite the small addition amount of 2.5at%. In addition, although a small Laves phase exists in the W element, a BCC type phase has been obtained as the main phase.
- FIG. 5 shows T i 4 . Shows the C r 57. 5 W 2. 5 hydrogen storage properties of the heat treated alloy. Like the Mo element, the W element-substituted alloy is almost a BCC-type single phase, and its hydrogen storage capacity reaches about 2.7 wt% or more. Since the W element has a large atomic weight, the hydrogen storage amount is slightly lower than the Mo element or V with the same amount of addition compared with the Mo element and V.
- FIGS. 6 and 7 show the effect of the added amount of the Mo element or the W element on the hydrogen storage characteristics in these Ti-Cr-Mo and Ti-Cr-W heat-treated alloys.
- the additive element is Mo
- the amount of hydrogen occlusion increases with the addition of a small amount of Mo element, and reaches a maximum at about 3 ⁇ 1.5 at%, and conversely, in the conventionally preferred range of 5 at% or more, It can be seen that the hydrogen storage capacity gradually decreases, and that the addition of 1 Oat% or more lowers the hydrogen storage capacity as compared with the heat-treated Ti-Cr alloy to which the Mo element is not added.
- the element to be added is W element
- the same tendency as that of the Mo element is observed, and the amount of hydrogen occlusion increases with the addition of a small amount of W element.
- the hydrogen storage capacity decreases gradually, and the addition of 6 at% or more lowers the hydrogen storage capacity compared to the heat-treated Ti-Cr alloy that does not add the W element. It turns out that it does.
- the addition of a small amount of the Mo element and the W element is intended to increase the volume ratio of the BCC type phase appearing in the Ti-Cr binary alloy. Comparing the strength of the BCC type formation tendency in the Ti-Cr alloy with the Mo element and the W element, it can be seen that the addition of a small amount tends to increase the volume ratio of the BCC type phase. It can be seen that if the amount is too large, the hydrogen storage amount per unit weight will be reduced.
- the Mo element and the W element are independently added to clarify the effect of the addition, but the present invention is not limited to this. May be added in combination. In this case, the total amount of the Mo element and the W element may be less than 5 at%.
