  ZrMn 2，ZrCr 2和相关体系的氢化物的形成和分解的量热焓

  摘要：

  通过超化学ZrMn吸收和氢解吸的积分焓2 Ť 0.8（Ť =锰，铁，钴，镍，和Cu）和化学计量的ZrMn 2 -和ZrCr 2种基合金已被确定。测得的焓范围为〜24至〜41 kJ /摩尔H 2。该ΔH由一系列金属主机形成氢化物值ZrMn 2 Ť 0.8是比用于ZrMn较小2，占ZrMn的增强离解压力2 Ť 0.8氢化物。在ZrMn 2 T 0.8系列中氢化物ZrMn 2 Co 0.8的氢化物极小，这说明该系统的分解压力极高。由已发表的中子衍射研究提供的位置占用率用于计算ZrCr 2氢化物和相关系统的结构熵。获得的结果与实验完全吻合。

  The reactions of H-2(g) with the two-phase alloys (a) alpha-Zr + ZrMn2 + x and (b) alpha-Mn + ZrMn2 + x have been investigated. The homogeneity range of the Laves phase ZrMn2 + x intermetallic compound has been determined from the dependence of its hydrogen absorption behavior upon x and found to lie within the limits x = -0.3 +/- 0.1 and 1.0 +/- 0.1. Normally H-2(g) does not react with alpha-Zr below about 773 K, but it has been found that when it exists within the two-phase mixture, it reacts readily with hydrogen at room temperature. For alloys in the zirconium-rich two-phase field the hydrogen first reacts to form ZrH approximately 2 and then it reacts with the ZrMn2 + x phase. The former reaction leads to equilibrium pressures which are too small to measure, but the latter leads to measurable pressures. Results for alloys within the manganese-rich two-phase field, x greater-than-or-equal-to 1.0, are also reported. Calorimetric determinations of the enthalpies of reaction with hydrogen for several zirconium-rich alloys within the two-phase fields are reported for both the zirconium-rich and ZrMn2 + x phases.

  The reaction of hydrogen with ZrMn2 + x has been investigated using reaction calorimetry for x = -0.2, 0, 0.5 and 1.0. The enthalpies for hydride formation and decomposition are equal in magnitude over the two-solid-phase region; their magnitudes decrease with increasing x. Hysteresis is large for all these intermetallics, approximately 3.0 kJ (mol H)-1, and independent of x.
