摘要
ZrCo合金由于优异的储氢性能以及安全特性,已被国际热核实验堆(ITER)研发团队选取为用于氢同位素快速储存与供给的重点备选材料。然而,由吸/放氢循环过程中发生的氢致歧化效应导致的储氢性能严重衰减,成为了ZrCo合金推广应用于氢同位素快速储存与供给的最大障碍。因此,改善ZrCo合金的抗氢致歧化性能对其广泛应用于氢同位素快速储存与供给领域具有重要意义。本文介绍了ZrCo合金的储氢性能和氢致歧化特性,综述了元素替代(掺杂元素部分替代Zr或Co)改善ZrCo合金抗歧化性能的研究进展,并指出进一步改善ZrCo合金抗歧化性能的必要性及可能的发展方向。
Owing to excellent hydrogen storage properties and safety characteristics,ZrCo alloy has been selected as an important candidate material for rapid storage and delivery of hydrogen isotopes by the ITER team.However,the hydrogen-induced disproportionation of ZrCo during the hydrogen absorption/desorption processes will cause serious degradation of hydrogen storage properties and has been considered to be the biggest obstacle to its wide application in rapid storage and delivery of hydrogen isotopes.Therefore,it＇s extremely significant to improve the anti-disproportionation property of ZrCo.In this paper,progress in research and development on the hydrogen storage properties of ZrCo as well as improving the anti-disproportionation property by element substitution of Hf,Sc,Ti,Ni,Fe are reviewed.Meanwhile,the possible development direction of further improving the anti-disproportionation property of ZrCo is proposed.
