  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。

  dissociation pressures of the ZrMn2T0.8 hydrides. In the series of ZrMn2T0.8 hydrides there is a pronounced minimum for hydride of ZrMn2Co0.8, accounting for the extraordinarily high decomposition pressure of this system. Site occupancies, provided by published neutron diffraction studies, were used to calculate configurational entropies of ZrCr2 hydrides and related systems. Results obtained were in fair agreement

  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.
