【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。
[Abstract]:Due to its excellent hydrogen storage and safety properties, ZrCo alloy has been selected as a key candidate for rapid storage and supply of hydrogen isotopes by the research and development team of the International Thermonuclear Experimental reactor. The serious attenuation of hydrogen storage performance due to the hydrogen-induced disproportionation during the hydrogen absorption / desorption cycle has become the biggest obstacle for the rapid storage and supply of hydrogen isotopes in ZrCo alloys. It is of great significance to improve the hydrogen resistance of ZrCo alloy for its wide application in the field of rapid storage and supply of hydrogen isotopes. This paper introduces the hydrogen storage properties and hydrogen disproportionation properties of ZrCo alloys. In this paper, the research progress of element substitution (doping element partially replacing Zr or Co) to improve the antidisproportionation performance of ZrCo alloy is reviewed, and the necessity and the possible development direction of further improving the antidisproportionation property of ZrCo alloy are pointed out.
