摘要

本文报告了铬/锰比对 Ti30V60Mn(10-x)Crx（x = 0、3.3、6.6 和 10）+ 4 wt.% Zr 合金热力学性质的影响。研究发现，焓和熵随 Cr/MN 比率的变化而变化，焓和熵的变化以焓熵补偿的方式耦合。利用补偿品质因数，可以确定焓熵补偿不是由于统计原因造成的，置信度超过 95%。

Entropy-Enthalpy Compensation in Ti-V-Mn-Cr BCC Alloys Used as Hydrogen Storage Materials

In this paper, we report the effect of the Cr/Mn ratio on the thermodynamic properties of Ti30V60Mn(10−x)Crx (x = 0, 3.3, 6.6 and 10) + 4 wt.% Zr alloys. It was found that the enthalpy and entropy change with the Cr/MN ratio and that the entropy and entropy variation is coupled in an enthalpy-entropy compensation fashion. Using a compensation quality factor, it was established that the enthalpy-entropy compensation is not due to a statistical origin, with a confidence of more than 95%.
