含Co稀土储氢合金相变研究数据集

本文章主要是面向低滞后高抗粉化能力的固态稀土储氢合金及其制备和应用，通过通过B侧Co含量添加降低了分阶段相转变的能垒，极大改善了合金吸放氢平台压滞后效应及其抗粉化能力，具体详细记录了相关材料的PCT曲线，粉化情况对比、稳态热分析ETA对于热力学相变行为的佐证与机理分析，数据量为39.10 MBThis work focuses on solid-state rare-earth hydrogen storage alloys with low hysteresis and high pulverization resistance, as well as their preparation and applications. By adjusting the Co content at the B-site of the alloy, the energy barrier for stepwise phase transitions is reduced, which significantly mitigates the hydrogen absorption/desorption plateau pressure hysteresis effect and improves the pulverization resistance of the alloys. The dataset includes detailed records of PCT curves of the relevant materials, comparisons of pulverization conditions, steady-state thermal analysis (ETA) results for corroborating thermodynamic phase transition behaviors and conducting mechanism analysis. The total data volume is 39.10 MB.
