Research on hydriding reaction kinetics mechanism of Mg2-xNdxNi (x = 0-0.3) alloys Qi Wan1, Ping Li1, Liqun Cui 1, Weina Zhang 1, Yunlong Li 1, Qu Xuanhui1，2 (1School of Material Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China; 2State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China) Email: bj60106531@sina.com Keywords: Mg based hydrogen storage alloy, vacuum induction melting, PCT curve, kinetics performance Abstract: Mg2-xNdxNi (x=0.1, 0.2, 0.3) alloys, along with Mg2Ni for comparison, were prepared by vacuum induction melting, The influent of content of Nd on the microstructure and hydrogen storage performance were studied, the hydrogenation mechanism of Mg2-xNdxNi alloys was explored.
Introduction Mg-based alloys are one of the most attractive and promising hydrogen storage materials.
Experiment The starting material were Mg (≥99.9%), Ni (≥99.9%), Nd (≥99.9%), used without further purification.
The materials were vacuum induction melting to obtain a Mg2-xNdxNi (x = 0.1, 0.2, 0.3) composition.
